best ways to get extra hp?

[Unbeliever]

For an upcoming game I've got an Archivist/Binder/Anima Mage (divine variant) who plays like a front-line combatant.  I know it's not super important for optimization purposes, but I'd love to get him some extra hp.  Besides the obvious, getting a high Con, what are the best ways to improve his hp total?

Heart of Earth^CM gives you CLx2 temporary hps and a swift action stoneskin for emergencies.  There are probably a few better options out there, but HoE is easy and my personal favorite.

Necrotic Empowerment from Libris Mortis (does require a feat) gives temporary HP.

Personal range, 8th level spell, 1 round/level (Persist anyone?).
+8 Enhancement bonus to Dex, Int and Wis, +8 Natural Armor, +5 competence bonus to Fort Saves and 100 temporary HP.
Does have the [Evil] tag though.
Ridiculous spell if you can manage to persist it somehow. Like, for example Vestige metamagic...

I think the easiest thing is to start stacking some temp hit points?  Empowered False Life, Empowered/Maximized Vampiric Touch (There's a weapon enhancement that auto-empower it, I think, from MIC), Troll Shape from SpC comes to my mind...

Holy crap, Necrotic Empowerment would be great.  The game is starting at 10th level, though, so it will be a while before I can manage that one.  Is there any way to get it before 16th level?  I might be able to generously get the DM to let me apply my feats or class features to an item, or I could even use some Artificer tricks maybe?

Do temp hp from multiple sources stack?

Do temp hp from multiple sources stack?

I think it is kind of a moot point. Even if they overlap, they're all still there... So if one set gets "used up", then the next one kicks in, etc. So while it might matter slightly, it wouldn't really make a big difference, and it is harder to track than letting them stack.

I think the RC said they stack, anyway, as long as they're not from the same source (like casting False Life 5 times, etc).

You remember correctly about this (page 72). Temporary hit points from the oldest effect are lost first, and when those are used up additional damage transitions smoothly to subtracting from the next oldest pool of temporary hit points.

Ring of Friend Shield (DMG-232) - you only take 1/2 damage and someone else takes the other 1/2.  In a lot of ways it's like doubling your hit points.  Of course, finding someone willing to take 1/2 your damage is another story.  The spell Shield Other (PHB-278) also does the same thing, but you have to stay close to each other, and you'd have to find someone to cast it on you rather than you cast it on another.

Just remember that temp HP from the same source doesn't stack, the highest total overwrites the other.
