Projectorcentral.com was my main source of information when selecting the projector, screen, and their vendors. Thanks for the valuable information on this site. My home theater is set up in the basement. The room is 13' by 20'. The room was finished with sound isolation in mind. The wall separating the home theater room and the adjacent rooms are double walled with fiberglass insulation in between for soundproofing. Because of wiring and plumbing on the ceiling, suspended ceiling system is used. This offers the opportunity to use acoustic tiles to significantly reduce the sound to the upper level. Suspended ceiling also makes wiring the home theater system a lot easier. There are two windows on one side of the room and a rear half glass door leading to the breezeway connecting the garage. I use room-darkening shades on the windows and the door to control the light for daytime viewing. The entrance to the room at the front is a full glass door. With this door closed, sound is confined to the theater room, except the occasional low frequency rumbles from the subwoofer if it is turned up high enough.
The room is an existing TV room with a 42" standard definition rear projection TV and a surround sound system, purchased about 4 years ago. We have decent sound, but a 42" 4:3 format TV just does not look right, especially when showing widescreen format DVDs. With the price of front projectors dropping to a more affordable level, and the availability of high definition program sources, it seems to be the right time to acquire a larger screen TV. I bought the system in November. A 108" Elite Screens motorized projection screen is installed to come down in front of the existing TV. I can still use the TV for watching news and other non-high definition TV programs. The source of high definition programs is from the cable TV tuner with a built in high definition Digital Video Recorder. The DVR is a wonderful feature. It records high definition programs with Dolby Digital surround sound as well. The cable tuner/DVR is rented from the cable service provider. It does not seem to make sense to buy this type of equipment, since technology moves so fast. The quality of this Elite Screens model seems unbeatable for the price. Before the installation of the screen, the center channel speaker was placed on a shelf on top of the TV. With the screen lowered, it muffled the center channel sound. Instead of spending a lot more on an acoustically transparent screen, my solution is to place the center channel speaker on the bottom shelf of the TV stand. It is not the ideal position, but it is a compromise.
When choosing the projector, I narrowed down to the Panasonic PT-AE700U and the Sanyo PLV-Z3 based on the reviews on the projectorcentral.com web site. The final decision was an easy one once I decided to mount the projector on the ceiling. The wider lens shift range of the Sanyo Z3 made flush mounting the projector to the ceiling possible. I did not want to use keystone correction.
I did the installation myself. I rewired the recess lightings in the room into 3 groups controlled by dimmers. When lights are turned off, the two rear lights can still be dimmed to a comfortable level, and yet post virtually no effect on the screen. I also wired one power outlet for the projector and another one for the screen inside the ceiling. The Peerless ceiling mount is mounted to the ceiling joist through the ceiling tile with a 2.25" threaded pipe and pipe flange purchased from the home center. The projector is mounted about 12 feet from the screen. The screen is also mounted directly to the ceiling joists through the ceiling tiles, using quarter inch threaded rods and angle irons. The nicely designed mounting system of the Elite Screens HOME series model makes the screen installation quite simple. I did not want the expense of the home theater seating. I kept the sofa and love seat set already in the room. I just replaced the legs of the sofa and love seat with chair casters, so that they can easily be moved around if needed for more comfortable viewing position. The sofa is positioned about 13 feet from the screen.
The audio system is about 4 years old and they are in great shape and produces excellent sound quality. All the speakers are Polk Audio speakers with models that maintain proper voice matching in the surround sound setup. Having a large screen is great, but I cannot stress enough that a decent Dolby Digital and DTS surround sound system is the other half of the home theater enjoyment. They complement each other.

Answer
First is the stuff to keep kids safe. You need a first aid kit, outlet covers, and safety locks for the cabinets. If you plan on taking toddlers invest in a toilet seat lock. A toddler is top-heavy and can easily drown in a toilet. You'll need a cot, mat, or crib for each child.
As to program- I know they are expensive but you really need a set of wooden unit blocks. They will last forever and offer great learning opportunities. You'll need accessories such as cars and trucks and people to go with them. A good sized dollhouse is always a draw.Go to discountschoolsupply.com for good deals.Sign up for their weekly e-mail. There are usually great sales. This is the best place to get consumables such as paint and paper. Their Colorations brand stuff is pretty good, but stick to crayola crayons.
You need a child sized table and chairs. If you are planning on taking babies invest in low chairs. They are like high chairs but they are on the same level as the table the kids use. It makes it much easier for everyone to have meals together.
You need puzzles, ranging from simple to more difficult. Also. manipulatives such as lego and other building sets.
Find a way to provide sand or water play. If you don't have room for a water table use a dishpan. Cover the table with a flannel-backed tablecloth, flannel side up. That will absorb spills.
You need a dramatic play area with a child-sized kitchen and all the accessories to go with it. Those cute kid sized pot and dishes are cute but you gewt more for your money and it is more realistic if you stock up at the dollar store. Don't forget some dress-ups for boys and girls.
Books and more books! Good books, not based on cartoon or TV characters. Provide a cozy corner of the room with some cushions as a reading area. Enrich it to a reading and writing area with a small desk with papers of all kinds, alphabet stamps, a picture dict0ionary, alphabet stencils, envelopes and stickers to use as stamps. A computer is nice but not a necessity. If you have one limit each child to 20 A puppet theatre encourages creativity and language development.minutes or less a day.
Some live plalnts and a small animal or some fish make the place look homey and provide science experiences.
An easel is imperative. If you don't have floor space you can find the ones that hang on the wall. You'll need the paint pots and brushes to go with it. The kids need access to art materials to allow them to create on their own, not just when you have planned an activity.
You can find lots of interesting toys at garage sales. Just clean them and sanitize them with a spray solution of a tablespoon of bleach in a quart of water.
You will find the work exhausting but a lot of fun. Good luck!.
