Assuming you're the one trading the Stepan/Ladd/Carlson/1st package, I would do either the Staal trade 1st, Gaborik 2nd.
Not sure why this would even be in question. You're trading parts for a top 20 player and a decent offencive D.
Staal's profile got a healthy boost this summer with the Jordan trade and the Semin signings. Worse case scenerio, you flip him based on hype and get a better return than what you paid for him.

And honestly, this is a no brainer. So if this the case of a deal you're 'thinking' of offering vs. a deal that has actually been offered, you need to go back to the drawing board.
