Moved to Trinity setup from Binary Tank/DPS setup - Healing help?

I just moved from a Paladin and 4 Elemental Shamans to a Paladin, 3 Elemental Shamans, and a Resto Shaman. I'm seeing the advantages so far, the healing that I had available before wasn't terribly good, and it killed my dps whenever I had to heal. Now I can continue to dps even when I'm healing. Right now I have a the following healing setup:

Heal shamans:
/cast [target=name] Lesser Healing Wave

Heal Paladin:
/castsequence [target=Tehtsara] Riptide, Lesser Healing Wave, Lesser Healing Wave, Lesser Healing Wave

Earthshield Refresh:
/castsequence [target=Tehtsara] Earth Shield, Water Shield

I put Water Shield in my Earthshield refresh macro to help keep Water Shield up from all those Lesser Healing Wave Procs. I've started to notice that with this trinity party setup my focus seems to be less on tanking and dpsing and more on healing. I have both my tank and dps shamans using one-button castsequence or castrandom macros and I just hammer on that button to manage them. All other effort is given to healing.

Could anyone share their resto shaman setups for multiboxing?

Well i play

paladin, elemental, elemental, resto, boomkin and i just need to spam 1 and 2.
On Keys 1 and 2 is my attack macro on all dps toons and my resto has an heal macro on Key 2. Key 3 is used for chainheal on all schamans

Well these are my german macros but can be changed easily.

Heal Paladin:
/castsequence [target=Tehtsara] Riptide, Healing Wave, Healing Wave,Healing Wave

Earthshield Refresh:
/castsequence [target=Tehtsara] Earth Shield, Water Shield,Earthliving Weapon

Why the big heals? My paladin's pretty much overgeared as hell for those instances, lessers are enough to top her off from time to time. Are they more mana efficient maybe? I was going with a "More lesser heals, more improved water shield procs" premise.
