Should I add Carlos Delgado if I already have 2 first basemen?

Do not do that trade. Drop Cameron, put Jackson in the OF, and pick up Delgado and put him at first. Then drop Napoli and pick up Volstad, he is a stud. Then maybe try and pull off a more reasonable trade to create a spot for Price. I don't really see anyone else you can drop. Keep Aviles, even though he has started slow. It is was too early in the season to be making any drastic moves. Try trading Tori Hunter and Kendrick for a better OF, or Zimmerman and Kendrick for a better 3b.
