Yes I have a few pointers I would like to share

Make some macros to shift into the different stances you like fx. Bear/Tree/Moonkins
Make sure you take good use of the [stance: 0/....] option or else you might end up shifting "out of sync" if one toon misses a key press.

Get Vuhdo+Isboxer (setup repeater regions)for healing. I previously had keybind healing on F1-F5. Vuhdo let me delete those macros and therefore giving me more keys for special abilities etc.
Bind macros in Vuhdo - again with the [stance:...] functions so your moonkins dosen't shift out and starts healing if you want a heal one of the toons.

Get flying form asap! Avoid collection quest you know.

Repeater regions + vuhdo really boosted my efficiency regarding healing by 60% or more. It enables me to take advantage of being able to heal with all toons if nessesary.

I hope this gave you some stuff to consider.

I'm no expert at all so it might not be the optimal solution, but hey it works for me.
