i have absolutely no experience with bonsai trees, but i want to get one. what do i need to know about growing one, what supplies do i need, and do i get seeds or buy one that is already growing?

There are thousands of books available. Research it my friend. It is a wonderful hobby. I used to "Bonsai" with my Mom. She has 4 green thumbs. And now that you've brought it up, I think I'll research some books myself and re-immerse myself in to it also! Thanks!!!
