Living/working in Fairfax can be like living/working in Westchester - you're near the city, but it's hard to get to, and the city is really where the GLBT action is - Dupont Circle, Logan Circle, the Shaw neighborhood and Capitol Hill. There are a couple of gay bars in the closer-in suburbs, but I don't think there are any out in Fairfax.
If you are going to be out in the burbs, you definately will need a car, but you might want to consider reverse commuting, if you want to be close in. Although I personally would never live or work in VA (known as the "Hate State" to many of us in the area), but only for political reasons (and No. VA is the only really blue part of the state), I do know that people like living in Arlington, which is much closer to the city, and has good access to Metro (in case you want to party in the city and not risk a DUI - the Metro system is open until 3AM on Fri and Sat night, midnight otherwise). The traffic in No. VA is pretty crazy, so a reverse commute might make sense, and invest in a good map (ADC has good local DC-area maps). Driving in both VA and DC - and Maryland for that matter - can be really confusing. Both Arlington and DC claim to have a grid system, for instance, but DC's numbered streets go North-South, in Arlington they go East-West - and that is just the beginning of the confusion. Once you are used to it, though, and find your way around, it isn't horrible.
As for housing, the market here has cooled, but both the rental and purchase markets are still very expensive. The house I bought in an "up-and-coming"neighborhood in 2003 has risen at least 30% in value in 3 1/2 years. VA has a lot of townhouse and condo communities, as noted above, so there are a lot of options. If you are thinking of buying, I can refer you to my agent, she was great to work with and very gay-friendly (she advertises heavily in the local gay rag - the Blade) - PM me if you want the contact info.
I agree with what you said.
I lived in the DC area for 3 years before moving up to the NYC area. I lived in both Arlington and Alexandra. Arlington is nice, and proximity to DC can't be beat. Alexandria is a little further away, but still a relatively quick trip to DC, and it would make your reverse commute to Fairfax a little easier. Of the two, I liked Alexandria more. However, when I worked in DC, the commute on the metro from Arlington was so quick, it was worth moving closer to the city for that. Even though I lived in Arlington, I never really hung up or did much there. I spent all of my time when I wasn't at home in DC or Alexandria (with the occassional trip to Great Falls, Baltimore, Rehobeth, Annapolis).
If you want the gay scene, you'll have to go to DC. For other nightlife, you're looking primarily at Arlington and Alexandria (with a little in Fairfax, as I recall, at the Town Center).
You'll probably want a car if you're working in Fairfax, though if you're located on a bus route or if you're lucky enough to be at a Metro stop, you can do without. But don't bother driving in DC... the Metro will take you most places you would want to go (Georgetown and Adams Morgan not withstanding). The Metro is great... one of the best systems in the world. I've ridden the subways in NYC, DC, Atlanta, Boston, Philadephia, Chicago, San Francisco, London, Paris... and while they all have their pluses and minuses, the DC Metro (and San Fran) are the two systems I ENJOY riding the most.
I really like the DC area, and sometimes I think I should move back... but NYC always has a pull on me that so far has kept me here. Have fun, and get out and see and do things. Too many people who live there don't take advantage of all there is to do in DC. Great museums, great performing arts venues, very good jazz club, better than average theater scene, the climate is conducive to lots of outdoor activities for a good part of the year. You're not far from camping in the mountains or on the shore (if you're into that), and the cities I mentioned above are great day trips. You're also close enough to hit Philly and NYC for the weekend.
