Albert's pick on ThemeForest is very good, but they've got a whole lot more to choose from, and for really good prices - this is where I got my template from:

If you haven't got a hosting site yet, I suggest FatCow - they're wind powered, so you can have a somewhat green website:

I'm in my second year of using them, and I really haven't had any problems.
