CB:  Skins should resign Carlos Rogers now.  No one else out there.  

T:  They also should go after Jared Gaithers and Jamal Brown.  Injuries have been killing this position for years.

QB:  Go ahead and sign Grossman.

LB:  Bring back Rocky and another ILB for depth.

This appears to be a year to develop the core team and then go from there.  They aren't going to be a playoff team and need to make moves for next year or the year after when they have their QB.
