Very cool addon I've found, well its been a while I found but just to decrease your pain in keybinding and placing skills all over again here you go:
Action Bar Saver 2 : WoWInterface Downloads : Action Bar Mods
what you do with it is basically that you place your skills -> keybind them, and
/abs save <name>
for example if you change a lot between private servers this is pretty useful, just
/abs restore <name>
Enjoy (I tried to search for this, I didnt find it anywhere, hope its not a repost)
