Ok here's my list. Sorry I don't exactly remember at what levels I did them. I'll post the most important strategic tips instead.

- Ramparts (split the dragon/dwarf fight, use grounding totems)
- Blood Furnace (before the last boss, continue to drop grounding totems to keep the last guy alive and busy until the debuff wears off)
- Slave Pens (earth elementals useful from this instance level on, focus the totems of the first boss, especially the healing totem)
- Mana Tombs (Max damage zerg)
- Sethekk Halls (last boss aggroes searing totems after AE, use them)
- Mechanar (second boss's adds also aggro fire elementals which are immune to their damage)
- Botanica (Max damage zerg, do not bother running out of LOS to prevent healing @ the second boss)
- Shattered Halls (Spread out and positioning is important for Bladefist, ignore second boss's aggro game and stay closely packed)
- Magister's Terrace (pretty tough overall, deal damage as fast as you can, focus on melees first, re-post grounding totems, use elementals for all bosses)
- Shadow Lab (Tremor totems for the first boss and minibosses, be quick on the second boss, ignore Murmur's debuff)
- Steamvault (nature resistance for first boss, the second boss can be zerged with fire elementals and CL, earth elementals for the last boss, ignore his enrage)

My healing setup is not all that sophisticated, Gallo. All characters will /stopcasting and start healing when I hit the respecitve button.
Type 1: lesser healing wave on focus
Type 2: chain heal, with toon1 targetting toon2, toon2 targetting toon3, and so on.
Type 3: lesser healing wave on focustarget

Since it's only lesser healing wave, the time loss for dealing damage is acceptable and the overall healing is sufficient for me.
Moreover, for tough fights where mana is not an issue, I set up five healing totems right after spelldamage was buffed by wrath of air and trinkets. The +heal scales into the totems for their entire lifetime, even after the trinket effects have worn off. Bug or not, I take advantage of that. So I get a passive healing of ~78 per tick times five.
