Kellie,
You shouldn't have much difficulty with those things, with the possible exception of the home. For that, I'd suggest talking to the ower/agent for directions from the airport. In general, I'd expect the directions to the house to tell you to leave the airport by the South exit and take 417 (aka Greenway) to exit 6. From there, I can't help you without knowing the location.
To get from the house to Disney, it will probably be simple enough to get on 192 drive to World Drive to get onto Disney property. The signs are pretty good for the four parks, so just follow the directions.
Going to Universal is almost as easy. You'll need to get on 192 to I-4 East. Follow that for about 15-20 miles and you'll see the signs for Universal. Sorry I can't give more specific directions than that, but I don't visit there.
Busch Gardens in Tampa is a bit over an hour away. I can get you over to Tampa (just get on I-4 West) but don't think I could get you to the park. Sorry.
KSC is a great place and easy to get to. From the house, get back on 417 (GreenWay) the same way you got from the airport. Drive back past the airport exit and keep going until you get to 528 (BeeLine) and take that east. It will pretty much take you all the way there. Just watch for signs as you get close.
