A large shield has a +2 armor bonus without any magical enhancements. If they are magical +2 shields then their total armor bonus is +4, not +3. So the total AC's for your characters are 26 and 34, respectively.
GralTok, I respectfully suggest your group rethinks your house rule for the Bracers of Armor. Having it stack with rings of protection is not a problem because you rarely see a ring with too high a bonus. But if they stack with armor, then they do become overpowered. Use your own character as an example.
