I can change out just one chain ring? Wow I learned something new today! If I change out my cassette will I have to change the deurailler (sp?) And chain too?

You'd have to check your cranks, but i think probably you can just change the 1 chain ring.

If you change out your cassette, you're supposed to get a new chain. Your rear derailleur can probably handle the 11-28 no problem, because my short cage ultegra one did on mine - but there's a slight chance you'll have to get a long cage rear derailleur.
