Hagelin, John Moore, Miller, Fast, Dorsett & Nash should be who the team looks to trade this summer.
Its clear that Lundqvist, McDonagh, Staal and Girardi are our cornerstone players and are who the Rangers need to build around. Obviously you do not see an offensive player in there. You get one more year of St. Louis, and then who knows. Stepan you might be able to throw in there, but I think you really need to get a center than can break entry through the zone. To use Colorado as an analogy, Stepan is the Rangers' Stastny, (one of the reasons I am against signing him as a free agent), but Stepan needs a MacKinnon/Duchene type to compliment him for match up purposes on another line. Stastny, is helped by having high level players on other scoring lines that have speed and skill, which in turn makes his well rounded game look better, as he isn't asked to carry to much of an offensive, play making role.
Now, we know that AV wants a net presense, and we know that AV needs a center than is capable of breaking the zone. While the players I mentioned in the first paragraph may or may not be attractive to everyone, you can target players of the style that the team lacks using them as bait. Its about getting the right pieces in, not the flashiest names.
If one of Haggerty, Bodie or McCarthy hits, not having a 2nd (or 1st) won't be an issue. If Richards is amnestied, and the money isn't wasted, then the cap drain wont be nearly as bad. If Nash can be moved for better assets then that won't necessarily hurt the cap either.
My two Nash moves that might make sense:
Nash and Hagelin (maybe a little more) to SJ for Pavelski and Havlat's expiring contract; desperate teams do crazy things, Thornton loves Nash, stranger things have happened
Nash, Stepan & Hagelin to CAR for Staal and Staal; Nash probably vetoes but I think that trade does wonders for both teams. Really gives Carolina a clean slate in terms of a rebuild/new identity. Eric and Jordan in NY gives the Rangers two kinds of players they desperately need. A legit 1C, and a defensive 2C that can anchor a checking line to platoon with the MZA line for offensive/defensive matchups; we know how AV likes to zone match.
Anyway that's my creative outburst for the day.
