WotLK So I'm 80, now what?

Looking for some guidance on gameplay, I now have several 80s.
All have only done PVE/questing and are geared with quest rewards and drops.
Aside from farming and working on rep, I'd like to break into some higher level activities but hard to w/o proper gearing.
What do I do now?

Also, I'm terrible at PVP, so that's something I would like to work on as well. Poor skill and gear make it difficult lol.
