Spend about a week grinding Heriocs (atleast intill you get full pve gear that your able to Do BH no problem, It took me about 15 hours played time.) once that is the case then Make sure you do BH every week. get into BH 25 man over 10 man, as there is less demand on you (unless your Tank/Healer, and even then maybe so)
Once you get there. and ready to gear for pvp.
First if you have the gold/time to spend buy/farm the mats to make the crafted pvp set. If that is not the case then your in for a grind Full honor gear. Grinding the honor was the way for me. Finding groups that was running premades will help but there not required. If you only have limited time to play Try and focus your time on the weekend. If it isnt AV, SOTA, Isle, do random bgs as most of the geared players are doing the bg weekend.
I found about a week (20+ hours played time) of good grinding, you will find yourself sitting good enough to join in 2s for conquest. When you start gearing for conquest. to Buy the items that DO NOT drop in Baradin's Hold. Head, Shoulder, Chest, Weapons, Once you get those times, I personally like to buy the most expensive peices first if you havent won them. And remember just cause you got the item from BH doesnt mean its the right item with the right stats for your spec.
I hope this helps. This is exactly what I did for greens to cata. (didnt get the crafted sets) about to do it again once I get another alt to 85.
