You might consider Andy Pafko as your Brooklyn Dodger. He didn't spend a long time with the Dodgers (a little over one and a half seasons) but he's identified with them by many people by his appearance in Roger Kahn's The Boys of Summer.
And you're probably right about using Glaus rather than Kent.
Most of the rest of your choices are quite good.
