As someone who has leveled a protection paladin (later raided as holy paladin) and is now protection again, I can only give limited advice for retribution paladins.
Retribution aura is (unfortunately) not good. It does not benefit from Judgement of Crusader. And the damage it deals does not scale. The higher you get it will fade away more and more.
Strength is more important to a paladin than anything. Strength gives you attack power, more attack power is always good. You will hit harder. If you hold a shield you will block better. Invest in strength. Strength is to a paladin what agility is for a a warrior or rogue.
Later on, you'll want to have equipment with spell power. Especially if your main tool of damage is Seal of Command. Spell power and spell critical rating is the way to go also for a holy paladin.
Your talent distribution for a raiding holy paladin looks solid to me. I would probably spec that way myself, if I would raid in the future. But I suspect that my raiding days are over. I expect to do more PVP now.
Redoubt is good. But you have to face your opponent for it to be effective. Put the points into Improved Devotion and Toughness to reach Kings. I would put the points for Hammer of Justice into Pure of Heart instead. Resisting curses and the like is much more important in Burning Crusade than anything else I guess. In my book Hammer of Justice is a PVP tool. Many bosses and some mobs in PVE are immune to stuns.
Well, the best way to do it is to go with your instincts and adjust with what your needs are. I usually re-spec when I think that my current equipment warrants it. Aura Mastery for instance does not stack with the three parts set bonus of Judgement (oddly enough), so I left it blank.
Edit: ah forgot... This would be my go at a retribution paladin.
