I use VuhDo to track my buffs from both Paladins and reapply them. I watch the party bars anyway for health/mana so I figured why not put the buffs on the bars also (I just press alt key and either right click or left click to apply the buffs I want per character as I go down the row). Some buffs you need to put in the URL for the proper rank from WoWhead but once that is done it has worked fine for me.
