Jason, you are correct that your needs are quite basic, and you should keep things simple.
Fast roaming is a specialized requirement that is only considered in very specific circumstances, and is not only NOT required for home use, it's pretty much unconfigurable for home use.
When you move from one AP to another, the worst that will happen is that you need to generate a new key, which is so quick it just won't affect anything you are doing.
There's a lot of technical information being offered in this thread, which is very well intentioned, however it just serves to confuse the issue - some of it is irrelevant, and some of it is technically wrong.
Just stick with a couple of access points that are manually configured and you'll be fine. If you have specific questions about how things work I'd be happy to explain.
