Hi and welcome!
There's been a lot of good advice posted before me, so I'm just goingto add some things. Have some basic idea about sizes ofbreeds, so you'll know how big they get and can get a big enoughcage. Most pet store cages made for rabbits will onlyaccomodate a single dwarf breed (if that), maybe something as big as amini rex which is still not very big at all. You could alsolook into building an NIC cage. If you get a wire bottom cagegive them something solid to rest on. Rabbits can belitterbox trained, especially if they are spayed/neutered.
Read up on rabbit diet and know what they need. Fiber isvery, very important but many popular commercial rabbit pellets don'thave enough.
Rabbits are very smart creatures and get bored in the traditional emptyhutch. Search the forum for toys- there are a lot of goodsuggestions. Many are free or cheap, such as a cardboard tubefrom toilet paper that is stuffed with hay.
If you want a spayed/neutered pet as opposed to a show bunny, lookaround at shelters in your area. More and more shelters aretaking in rabbits. I'm adopting one from a local sheltertomorrow.
Since they are already spayed/neutered, you'llhave a better idea of their personality than you would with an 8 weekold baby. They can also have a wide variety of breeds, so youmight be able to find a specific breed that you are looking for.
You're off to a good start. I'm really glad you asked aboutcare before you got your rabbit. When you get her (or him)tell us all about her and give us pictures if you can. Welove hearing about other people's rabbits here.
