You're right on the aura. My mistake. This still brings the AC of this character into the mid-50's (specifically 55, but with the possibility of going higher), which IMHO is a good place to be.
As for the +2 dex tome, I didn't want to assume any +2 tomes because this depends on what the original op has saved up, though I agree with you that a +2 dex tome would be nice. However even if a +2 dex tome is available, as Halflings start at a 10 base dex, and points into dex up to 16 are only 1 creation point each, I would still recommend to start with a 16 dex. Actually, a +2 dex tome would be ideal as this would bring a starting 16 dex up to a final dex to 26 for one more to AC.
Certainly all of these stats should be tweaked based on what tomes are available. Ultimately I think this is a decent build achieving most of what the original op wanted, with the exception of remaining pure Paladin
AC
Mid 50s at end game. I think this is good for a TWF build
Damage
Moderate DPS, which is about the best you can expect on a Paladin. Though the strength is low at 24, this build has a 24 Charisma and should utilize the new exhalted smite and divine sacrifice, along with using extended divine favor and zeal as needed
Saves
Excellent saves.
Solo Ability
This build should be fairly survivable, with a decent AC, moderate DPS, excellent saves and most importantly evasion.
UMD
Check. Enough intelligence is taken to put 1/2 point in at every level. Combined with a 24 Charisma, UMD should be decent.
LOH
Check, as this build is primarily Paladin
To the original op, hope this helps! Feel free to tweak as you see fit
