I went to www.outproud.org a lot right when I started questioning. There are some good online brochures and articles there. It hasn't been updated in a REALLY long time, but it's still a good source of basic info.

I think the PFLAG site has some info as well.

I don't remember the other sites I looked at back then, but I found that once I'd read all the introductory brochures several times, I started to be more interested in sites like Oasis. I needed something that went beyond "it's OK, you're normal, this is how you might be able to tell," and things like that.

These websites aren't really about coming out but could definately help you with 'being new to the community'.

afterellen.com (lesbian/bi stuff mostly, i love it)

afterelton.com (gay guy stuff, never really checked it out but as far as i can tell its the men equivalent to afterellen)

Theres a lot off good articles and videos and most, if not all relate to lgbt stuff.
Hope these helped :)
