Favorite Breeds: English Lop, Lionhead (wool breed, requires grooming), New Zealands (big bunnies), Polish (sweet little dwarf), and Dutch.
I'd have to know what it is you want from your pet (low maintenance, big/small, any little kids in your family, cuddler) to make a recommendation. Each breed has it's pros and cons. Also, every rabbit is an individual!
I feed purina rabbit chow, the show formula. I don't show my buns, but it has the best nutrition out of our local options.
Toys don't have to be anything majorly expensive. Ours LOVE soda boxes, macaroni boxes, tissue boxes, or cardboard tubes stuffed with hay!
I also offered pesticide free apple or pear twigs from the yard for them to chew on.
Rabbits in the petstore can be anywhere from 5 weeks (way too young to be away from momma) to about 3 months. I would recommend going to a reputable breeder, you'll be able to meet the parents and siblings of your rabbit, and you'll have an idea of what kind of temperament they'll have.
I feed timothy, or orchard grass. If alfalfa isn't in your pellets, and your rabbit is under 6 months, you'll have to find a way to supplement with alfalfa (I had to choose the pellets, Swiffer won't eat alfalfa hay)
I get most of my supplies from Tractor Supply Co.
Good luck! Rabbits are a lot of fun!
