Cool strategy. I should also say that getting new gear isn't the only way to up one's dps. I constantly read about my class, see if there's some better way I could reforge, if I should try a different glyph or just to make sure my rotation is optimal. Stuff like reworking keybinds helped me a lot too, or maybe looking into class specific addons. (I wouldn't even want to play a fire mage without mage nuggets and combustion helper.)
As far as gearing up goes, I'm always available to help out with heroics and such, as I know pugging those solo can be painful at times. Oh, and for those who don't know, something that's becoming pretty popular are websites that tell you exactly how you should gear/gem/reforge/enchant your character. Stuff like
http://www.askmrrobot.com/wow/gear http://rawr.codeplex.com/ or
http://www.simulationcraft.org/. I personnaly rarely use those, as I like to do the math myself, but it did up my dps the one time I tred it out. Basically, those things will calculate every possible way you can optimise a character and tell you the best one.
Anyways, we had a cool attempt on Beth'tilac, and I can't wait to try her out again.
