I'll weigh in here on the living situation. I work about 2 blocks from GW and live in VA, no where near a metro (I'm close to Pentagon and Pentagon City). There are however several bus lines, one of which takes me directly from my door to work. I pay about $1325 for a 2 bed, 2.5 bath condo with 2 parking spaces (pre-util) Since GW is has it's own Metro stop, you should seriously consider living in VA or MD. I had a friend that lived in Ballston for 2 years while he went to GW and had little to no problems. It does help to have a car if you live farther out, but Arlington and Silver Spring are pretty urban themselves so you shouldn't have too many issues. It takes me anywhere from 20-45 minutes to get to work depending on traffic, metro is around 30 depending on if I catch a train right away. Plus Arlington at least is crawling with Young Professionals and students. Huzzah.
