I would take a look at the domain feats from Complete Champion. The Chaos one(fits Kirrg better than the law one) is neat. You roll a d6(d8 at 10th level), and every round for a minute you gain a bonus on attack rolls(if the result of the d6 is even) or to AC(if it is odd) you roll every round so the bonus could potentially change every round. You can use it more than once per day if you expend 3 turn attempts. The destruction domain also is cool. Activate it as an immediate action and every attack you land for a minute reduces the creature's armor or natural armor bonus to AC by 1(2 at 10th level). These stack, so if you hit a creature three rounds in a row, it's AC is dropped by three after your turn on the third round. You can use this one an additional time per day for every turn attempt you choose to expend.
Rhun have you looked at oversized two weapon fighting as well? Imp Init is very good too though.
I took another stance as my feat. While I'm in it, every time an opponent misses me in melee I gain a +2 bonus to AC, this stacks for every attack. If I get attacked three times in a round for example and the first guy misses me, my AC goes to 22 for the second guy, if second guy misses if goes up to 24 for the third guy.
