this site has some great advice on everything Bonsai. Here's the page for their suggestions for indoor Bonsai.

But it depends on what you like. Every artist/hobbyist has a preference to which style, and species they prefer more than others.
The only tree that I've kept inside is my 12 year old ficus that I've only recently (the past month) attempted to train for Bonsai. I like the outdoor trees. There's more variety. Trees are meant to be outside (IMHO).
I have about 7 books that I'm currently reading. All on Bonsai, and between them and hands on experience like a beginner class, I've learned a lot.
