FCs and Linkshells are simple enough to explain once you get to that. You'll probably get a few FC invites as you play just because people will notice you don't have one.
My main recommendation is to just proceed with the main story of the game up until you unlock the ability to travel between the three major cities. A lot of the base gameplay mechanics are explained during that and should help get you up to speed in playing the game itself.
As for RP, the usual recommended place to lurk around to see other people RP and perhaps be pulled into some of your own is the Quicksand - where the Adventurer's Guild in Ul'dah is housed. If you start your character in Ul'dah, you'll be directed there to speak to Momodi right off the bat, though you will still be directed there anyway in the MSQ if you're not as part of gaining access to all three cities.
Once you're there, just see what everyone is doing. They'll be talking, emoting, and all that. I'm usually around there on Chachanji, so if you see the little green-haired Lala running around there, I'd be more than willing to help out with some beginner RP.
And even if I'm not there, I'm sure someone will be around and willing to interact with you.
