I shall leave the finer points of alignment up to the philosophers. 
I still am not following you on the pearls.
Each pearl, when activated (as a standard action), recovers a spell slot that had previously been expended. They don't provide bonus spell slots. Having 2 1st level pearls of power just means you can recover 2 1st level slots, after you use them. So, for example, if I cast Faerie Fire, then need it, I can use a Pearl and recover it. Then I need a Produce Flame, but I cast them already...I can recover one of those.
Useful for repeat-casting lower level heals and spells like remove disease and so on.
