As Amberionn said go for the Cloak of the Spirit Tracker. It's a pretty easy thing to do with guildies and can be knocked out in 2-3 hours. The gloves and bracer, although not your biggest need, can be upgraded to Serpents Spine Tier 1 at the Sunderock elemental camp(although they're not the really good upgrades until you get the powersources for them). If you can afford it, the Grandmasters Breastplate will hold you over for a good while. There is also droppable/attunable gear from Serpents Spine for sale in the Bazaar. Of note is the Heart of Ice Ring

I'm a non-raider so all of my gear is from single groupable content.
http://eq.testmagelo.com/profile/197105 if you have any questions about obtaining any of that gear I'd be happy to tell you anything I can. I'm also on BB and have had some plate gear rot recently so I'll keep an eye out for you if something else drops.
As for arrows, I'm afraid I can't help you there. I haven't used my bow in a very long time.
