Looking to "twink" an alt for fun, currently capped at 11. Any tips?

After seeing many low level characters burst through dungeons while max me barely registered on the charts, I wanted to have a bit of fun. I currently have a Frost DK with dual-wield, each with two gems plus standard razorice/fallen crusader combo.

Where would the current best blue gear be available from as well as tips on enchants? TIA!
