Hi Kim,
Contrary to what the other posters think, research has shown that children who attend preschool - even for one year of pre-K - do significantly better in school. And just ask any kindergarten teacher if she can tell the difference between children who have or haven't been to preschool. The benefits are social and behavioral, on one level, and attitudinal on another - children are excited, not afraid, about what a school day has to offer. This is the kind of attitude you want.
Okay, I'm off my rant. You should tour some schools to narrow the type of school you're looking for - there is a very wide variety, and no, they don't all teach the same things. There are plenty of preschools in the greater Fairfax area, but since you're a working mom and will need full time at some point, I would strongly recommend that you take a look at the JCC. Don't bother with preschools attached to private elementary schools unless you're going to go to private school later on. And the thing about waiting lists - with sibling preference, some schools are really full years ahead. This is still the reality - preschools are small!
Good luck! I'm sure you'll find a lovely school for your baby.
