The things I can usefully say are small. I've been around another friend who did this kind of search, but she had totally different issues and requirements.

My takeaway from that was that it's hard, that it'll probably be good for you, and if you want to try another church, there's a methodist church in arlington you might try. I think it's the Calvary church? It's right on mass ave. They seem very family-oriented, which may not be what you're into.
