Jamba for things like usable items {lance, pick-up quest starters, quest /use items}. For example, my horde lance for AT dailies in slot 1. Goes in the same place every day automatically. CTRL-NumPad1, they all equip the lance. Then I have an equipment set and a macro :

#show 16
/equipset reg

The #show 16 part displays what is in my mainhand slot and clicking the macro puts my normal gearset for all toons.
