Hoping to see if any of you can give a few insight on Comiskey Park for a day game.

1) Do they have batting practice during day games during the weekday?
2) Best place for autographs for visiting team? (Are you even able to get any at the park?)
3) What time do gates open?
4) Things to look at/places to go in the park?
5) Must eats?
Most importantly...
6) Do they sell game used items from that day (ie balls)?
7) Where is the game used booth/store location?

Thanks for the help!
