I had originally created this list for a guildie who wanted to gear up to start doing Karazhan on an alt but didn't know the best choices to gear up. I have provided a list of gear that will give the greatest DPS performance without relying on doing heroics or any other raiding or tradeskill dependent. Hopefully this can be of some use to anyone else with a new level 70 rogue trying to get ready for Karazhan.
The spreadsheet can be seen here:
