Feats to improve animate dead?

[Falling Icicle]

I'm planning on taking The Dead Rise invocation (mimics animate dead) for my Warlock character soon. I was wondering if there are any feats that improve undead summoning, such as being able to control more HD at a time, having stronger minions, etc?

[Edit] Also, is there any way to get Rebuke Undead without multiclassing?

Libris Mortis has a number of feats that make undead you create better, starting with Corpsecrafter (no prereqs, gives them +4 enhancement to Str and +2 hp/HD). Technically, it affects undead raised or created by necromantic spells, but a DM that would deny you the effects of the feat just because you use an invocation and not a spell would be overly ruleslawyery.

As for the rebuking thing, none that I know of.
