With your one non-core thing, I'd pick Bone Knight from Five Nations without looking back. Out of your feats, Greatsword is obviously a "sub optimal" weapon since it doesn't provide reach, but OH WELL! At least you get to cast Magic Vestment and Divine Power once a day from your War Domain. You have Power Attack which is all you'll need for damage in core. Cleave is nicer with reach, but you can buy CL1 potions of Enlarge Person for 50g each, so you get reach that way.
If you can get rid of Quicken Spell, I'd look to pick up Blind-Fight, Improved Initiative, Great Fortitude, or Improved Bull Rush. Ideally you could get to Improved Trip, but not with that Intelligence.
