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.

"The people who tell me they hate baseball or are out of baseball, they sound bitter about it. But I think that they sense what they’re missing. I think that they feel that there’s something their not in on, which is a terrible loss and I’m sorry for them." - Roger Angell
