Couple of questions from a noob

MistakeNot already got #2 so I'll take this one...

You can pvp together with your friend, GCs don't matter. In fact, thanks to queue abuse, now it's impossible to intentionally pvp for your GC. It's basically an accident of RNG if you end up on the same team as the GC you signed up for.

Thanks for this. I was curious about this as well.
