Generally i am not as magnanimous as this because Learning to build is a part of Player experience but since i have a similar character here is a build for you.
An easy build since you don't care about trapskills
Use two handed weapons or a Rapier and Shield at level 1 and 2, you can start dual wielding at level 3, before that its not really worth it.
Forget about Hide and Move Silent, you will not want to use that in groups.
UMD Very Important.
You can choose to put points in Open Lock instead of Balance for those odd locked chests when there is no rogue around, but Balance can save your life.
All you will need is a +1 dex tome at level 11, by then you should have enough plat to buy one at the AH.
The last level up is in Charisma because its a lot easier getting a +3 tome than a +4, and you can always lesser reincarnate if you ever get one.
When you hit Cap you might want to rethink the enhancements, i use all the Pally auras to help the party, but you can take out the AC aura by then to put in Divine Might 3 and 4 (after you get +2 and +3 tomes), so just reajust those enhancements the way you want when the time comes.
