On AA vs. OotB
I failed my will save. My character is a Rogue/Fighter/Holy Liberator/Order of the Bow Initiate/Templar (3/4/5/7/1)!
I considered AA but just found that OotB, even though I will never reach the max class level for it, is better for the stacking with rogue sneak attack, and my good wisdom bonus (for the zen archery thing). AA is much more a wizard thing, and I find it hard just to take a few levels of wizard. Having said that, at the moment I am in the middle of the largest battle so far, and against about 7 20th level wizard (some with prestige classes) I am struggling to do much, so maybe the wizard levels would have helped?
Go for obscuring mist, as its one of the few area spells at low level. Grease is fun too. You might want to allow touch spells to be imbued onto the arrows too if you are struggling (this makes much more sense to me anyway!) so then you can shocking grasp =).
