Okay, here we go:
Depending on how you feel about your current healt pool, consider Whisperwind Headdress, Holy Shroud, a +15 BoE mail helm, or the engi helm.
Neck should indeed be a erulean Talisman of the Eagle, but if you cant find a one a River pride choker works a little better too, replacing some of the stam you'll lose from chainging your helm.
Cloak enchant - I recommend +10 SR.
Bracers are fine, but I prefer [item]Spidertank Oilrag[/item] with +15 sp. You lose 2 stam and some armor but gain 3 mp5.
Gloves should be a +13 mail or leather or cloth (till you get higher ac class ones) BoE with +16 sp. 7/7 eagle gloves work as well.
Belt should be Girdle, if you need the mana [item]moss cinch[/item], a +13 leather belt, a +12 mail belt, or a 7/7 eagle mail belt.
Boots should be Defilers with 7 stam, [item]Gnomebot Operating Boots[/item] with +7 stam or runspeed and another pair with +spirit, and a +11 stam with +7 stam on them for debuff FCing
Spidersilk arent *bad*, however I'd still go with runspeed.
Trinkets: Get some other trinket to fill the AGM spot while you farm arena. A BoA would be ideal, but an AB shield trinket is useful as well.
Get a Zealot Blade with +22 int to start fights with, if you are at all concerned about mana.
Get a +7 sp shield with vitality to switch to once you're down a bit of hp, or desperately need the healing output.
