>Is there some tips for fitting in so I can pretend to be confident enough to at least walk in?
Man they will be happy to have a newcomer unless you're in a freaky backwards church, you don't have to try to fit in as if you've been there 10 years. They'll know you're new. It's what I did, just walked into a Catholic church and sat down in the pew, no prior research just learned by imitation. All you really have to know beforehand is the rules for Eucharist in whatever denom you're going for and to respect them.
