Retribution Paladin legs gear is current for Cataclysm.  I have compiled a list of legs slot gear pieces Ret Paladins can acquire, and will continue to build upon this list as we further ourselves into the Cataclysm expansion.

I have listed the legs gear into a Best in Slot format, with the best pieces listed at the top.  I am trying to factor reforging into this, but ultimately, the original primary and secondary stat prioritization usually wins out. 

For instance, two legs gear pieces with equal strength may have 100 crit and 100 mastery, or 100 hit and 100 mastery.  The hit takes priority over crit, unless hit capped, at which point the crit piece would jump ahead.  Reforging adds a minor adjustment in most cases.

This information may not be entirely accurate or complete in the early stages of Cataclysm, and I will continue to make adjustments as data is released.
