Well I caved. Last year, I knew I wasn't going to have time to get geared/raid/powerlevel into Ulduar... but then I wanted heirlooms, and to get heirlooms, you need argent crusade reputation [rep], and to get rep you have to do heroics, and to do heroics, you can't be the tard in all blues.

I also changed spec to destruction, and now my little lock is at 1750 spell damage. It's a big boost from 1499, and I am really mowing things down in as little as 2-3 buttons.

Last night, I got in groups for heroic Nexus and heroic Utgarde Keep. Each dropped about 2000 rep, so now I'm cruising at 18500. I will shoot for an instance tonight and with a few dailiestomorrow, I should be exalted.
