1. Yes. That is actually the only thing all atheists have in common: they don't believe in gods.
2. Yes. That is implied by belonging to a religion.
I am an atheist with buddhist tendencies. I wouldn't call myself religious (just as I wouldn't call myself a buddhist) but would call myself a spiritual person. Not spiritual in the ghosts and dryads kind of way, but simply recognizing I am connected to the world around me in a firmly non-metaphysical way.
