That's a nice looking team. You can use some extra power for sure and that's what I'd focus on. Since you already have Young and Cantu you may want to make sure you try for high average guys when looking for that extra oomph.
Also, since your starters are basically set like you said, now's the time in the draft to look for high upside guys that may not get much playing time yet but could develop into stars sometime soon.
