Oh, and forgot, don't bother with adamantite figurine, do the netherstorm for dabiri's enigma, better tank trinket in my opinion. Get a khorium destroyer crafted, big EH improvement. If you are looking for more avoidance, I would work on mech till you feel comfortable with running it on heroic. It is the easiest heroic IMO, so 4 quick badges, plus sun eater > fireguard, or even blazeguard for your gear. With the PVP pieces you are wearing, threat should not be an issue so do not worry about switching weapons. SSO rep neck would be very nice for you. Everything else you should pick up from kara or badge gear.
Got [item]dabiri's enigma[/item] actually, I use it with my [item]Regal Protectorate[/item] as my second trinket.
For the gun, I guess I could craft one at the same time I would craft the eng helm. (I just need to have my alt ding 70, it's at 64 currenlty, on the day it will ding 70 I'll buy it's epic flyer and drop mining on shel)
