Generally, I’d say I do pretty well in WPvP. If I attack first, chances are that I’ll win. If I don’t attack first, that’s when it’s CD dependent.
I had a ret pally 2 levels higher attack me while questing the other day. He almost killed me in the stunlock alone. Fortunately, vanish was available, stealthed up, healed, destroyed him… repeatedly. I am combat spec might I add, so not really set up for PvP at all. He dropped incredibly fast…this was not skill, just the class. Such high single target dps.
If a mage snares you, break with sprint. Lock/priest fear, wotf. Another rogue or druid, rupture him. When a pally bubbles, run 20 feet, bandage up, and /laugh…then stealth up and stun him again. Low on health? Gouge or blind, bandage. What I like about rogue is that there is an answer for everything. Definitely bandage dependent though, which I don’t mind at all. Warriors are the biggest challenge for me…especially when they charge first and dot me up.
I’m sure nobody would want this comparison, but I’ll say it shamelessly: this feels like the equivalent to a DH in retail. It’s a simple rotation… just requires a ton of patience and proper timing of skills. IE don’t do what I do sometimes…waste a sprint to break snare, then get snared again right after lol.
With gear at 60, I imagine a PvP spec will be required. Though I imagine you’ll go with one since that is your main focus… I’ll have to figure the balance out 
Also if you’re interested in herb/alch, it’s a great choice IMO. Not just to make your own pots–I had the gold for my mount before 40 (between that and a few SM pick pocketing runs).
Edit: Just to add, stealth feels super weak compared to in retail–especially at first. Without putting points into Master of Deception, everyone seems to see through it…from like 30 yards away. Once you get stealth rank 2, this is noticeably less of a problem. Do not ever expect, as a low level, to be able to hide from a 60 using it… especially humans. They’ll just see standing there shaking. I generally stealth in a bush when I can.
