For regional feats, I agree that Thug (+2 Init, +2 Intimidate) is strong. You might also consider Bullheaded (+1 Will saves, +2 Intimidate) or Foe Hunter (+1 damage against designated foes).
As the Champion of Gwynharwyf (CoG) rages stack with barbarian rages, I think Bbn 4 (rage 2/day) is enough. But, if you feel strongly about getting Improved Uncanny Dodge (can't be flanked), go to Bbn 5.
To get into CoG as quickly as possible you would then want one or two levels of fighter, giving you some bonus feats. So: Bbn4/Ft2 or Bbn5/Ftr1 gets you ready for entering the CoG PrC. (Remember to max out Intimidate as you go.)
Your feat selection is somewhat constrained in this build; Bbn4/Ftr2 gives you five feats (3 general, 2 fighter bonus) and Bbn5/Ftr1 gives you four feats (3 general, 1 fighter bonus). You know what you want three of the feats to be: Righteous Wrath, Knight of Stars, and Power Attack. You should use a fighter bonus feat for Power Attack, and the exalted feats take up two of your general feats. That leaves one general feat (= regional feat or Exotic Weapon Proficiency) and either zero or one fighter bonus feat (= Two-Weapon Fighting or Resounding Blow).
If you are going to wait to enter CoG, you could go to Bbn4/Ftr4 or Bbn5/Ftr4, in either case taking Weapon Specialization as the 4th-level fighter bonus feat.
So... Bbn4/Ftr4/CoG10/xxx2 or Bbn5/Ftr4/CoG10/xxx1. If you wanted to be cheesy you could throw in Rgr2 at the front end of the first build, which would get you Two-Weapon Fighting without spending a feat on it. You mentioned a desire for Annointed Knight, but I think that's going to be quite difficult given the Knight's skills pre-reqs. Otherwise, any Good BAB class would make a fine addition to Daelan -- you could even dip back into barbarian or fighter for abilities or feats.
As far as abilities go, do not negelect Charisma! Two CoG abilities are tied to it (smite evil and divine grace), and if you take Resounding Blow you'll want a good Cha for that, too.
I think Wis 12 is enough to start with, if you want to cast spells at all. That will get you a bonus spell at CoG1, and allow you to cast 2nd-level CoG spells at CoG4. Try to pick up a periapt of wisdom +2 at some point so you can eventually cast 4th-level CoG spells - the prizes here are death ward, holy sword, and possibly also sword of conscience if you are going to be fighting evil foes a lot.
Actually this build suffers from some pretty serious multiple-ability dependency, as you want good stats in every ability except Int. (Although as noted above you can get by with lower Str/Con thanks to rage.)
Daelan is a great NPC in Neverwinter Nights and your version of him seems like it will be both flavorful and effective. Have fun!
