On honor alone, you can purchase a full set of Hateful gear.
I believe Deadly is better, but that requires either VoA 25-man or a combination of Arena/Honor points and minimum Arena rating.

If you're going for maximum honor gains, generally AV is better honor per hour then the others.
Without a premade, which is generally ~500 min resiliency per toon, even on bonus weekends, AV is the most honor per hour.
Maybe you'll find another BG is better then this, it might vary in your battlegroup.

If you're willing to mix it up, doing the quest where you turn in 1 mark each from AB, AV, WSG, and SotA is probably faster honor.
Since you get 3 marks for a win, and 1 for a loss, you'll usually have a differing number of marks.
Do whichever battleground you have the fewest marks from, and turn the quest in whenever you can.
The first time is gold and 1241 honor. Thereafter it is just honor, but still very worthwhile. You can do it as often per day as you'd like.
Gloves are a good first piece, as they reduce the mana/energy of a move, or increase range etc. IE, give your toons a pvp bonus.
Two pieces is resilience bonus.

Gear comes in time.
A lot of classes have success by mixing in PvE (raid/heroic/badge) gear with their PvP stuff.
Experiment and see what you enjoy doing and what works for you.
