You don't really need more than that as it's unlikely you'd run out of power on more than 2 controllers at once.
Eneloop batteries are much better than standard NiMH batteries. They hold their charge for a long time even when not in use and not being charged.
I agree 100%.
Eneloop batteries rock. Skip the Duracells. Energizers are okay. I have ordered several packs of the Eneloops (we have a 5-year-old who has lots of toys that require the AA's, also), and have always been happy with them.
Get a LaCrosse Technologies charger. It has different modes for charging (lower amps means longer charge times, but makes your batteries last longer).
Also, the charger should have adapters that allow you to transform your AA batteries into C or D-size batteries.
Those quick-charge kits are horrible for your batteries, and will severly limit the amount of times you can recharge them.
