I don't think you can neglect the defense, our defense is really really poor. Certainly getting people back helps, but we need to add a number of starters too.
We can do bend but don't break, but not too well, we break far too often.
Offensively, I think the biggest gap is RT. Fix that, and we're doing ok. We could certainly upgrade the guards, and a blocking RB would be great, but our offense is decent even without those. The biggest thing at WR is probably someone to replace Moss if he retires/is cut. One of our young guys might step up, but I'm unsure of that.
Offseason wishlist is pretty much the same as it's been most of the year, S, RT, CB, ILB, and maybe DE, NT, WR, OLB.
