So it sounds like you're going for a more monkish build than a paladin-y build...what are you hoping to get from the paladin side of the build?
Since I would be wearing heavy armor, I would take spell reflection instead of normal evasion, mythril will free up dexterity allowing me to use it a few times a day. I can buy a ring of evasion Basically the stuff in which ascetic knight allows me to stack with monk levels lay on hands and smite. Lay on hands power the devastating touch attack. As I said then full out gray guard.
