Which should give you some pointers about spec, glyphs and enchants.

As a fresh 80, you'll probably get stomped a lot, but once you build up your pvp set, it should happen progressively less and less.

Do the WG weekly quests (approx 20K honor) and whichever BG's you like doing and you should be able to grind out honor enough to buy a few pieces fairly quickly.

Arena Season 8 will be here in a few weeks, so save your honor until then.

Hope this helps...
