Priorities for fixing this team? WHIR

[123inningplz]

20 team, 30 man roster, 6x6, h2h dynasty league.

We have our first prospects draft sometime this offseason (5 rounds) and I wanted some feedback on what to target. I'm looking into replacing Amezaga @ 2B and such. Also, I want to deal Giambi for pitching and a draft pick(s) since I doubt he has more than 1 good year left. Should I deal pitching to fill hitting holes and then draft heavy on pitchers or what? I have the 9th overall pick so I really doubt Gordon, Butler, or Wood will be available.
