Need set up for lvl 41 twink rogue :)

Hey guys! New pvp player, old pve ;) I have a few questions and would appreciate if someone could get me going in this pvp world
First of all, I never pvp'd so I need a set up in terms of skills, skill points, pets (preferably legendary and mythic as I spent all my money on gear :))
Secondly I would like to know where the general stats of people around that lvl so I don't get destroyed.
And lastly, any basic tips (skill set order for combos, different set up, etc) would awesome! Anything that would help me jump the learning curve.
Thx again!

I think most guilds at this bracket have left, so it's mostly inactive now.
