Redbud and Evermann are actually kinda scary. The only way to get to campus is via a bus that rarely comes (tops I believe 2 times an hour). You can walk, but it is a good 2 miles to 3rd street or so. And coming back it is worse - all uphill. The places are old and scary and they look like the balconies are made of barbed wire. Mostly the people who live there are international students (particularly those from Asian countries) who could not find housing elsewhere due to visas, etc. I had a friend who lived in Evermann and it was not a nice place to live. The only decent housing is for families and I wouldn't recommend that.
Wilkie is the "grown up" dorm for the undergrads. It is very antisocial and set up like a hotel. The rooms have twin beds and typical dorm furniture. It is a very nice dorm, but not my idea of a good time as a grad. There is another dorm now that is apartment style right next to my old dorm (where I lived last year). It is brand new (will just be opening in the fall), but VERY expensive. For the price, you can find something nicer without undergrads. If you don't have a car, good luck. Bloomington is not very transit-friendly. Your best bet is to get on the 9 route if you need to grocery shop. Somewhere near there is best. Most of the shops are on the East or West side and a GOOD ways from campus. Bloomington is pretty cycle friendly, so that is a good middle-road option, just make sure you get a damn good lock.
