For your next mod, I would consider a tuner or a tq converter. The valvebody is nice for the faster shifts, but it isn't going to make your truck noticeable quicker like the Tuner or converter will.
With you having a 2010, I would consider the Superchips Flashpaq if you plan to keep it simple, or go with Diablo with a custom Hemifever tune if you plan to go all out with the truck. The Superchips is cheaper at only $339, but Hemifever will be able to pull out a few extra hp for you with his custom tuning.
As for the throttle body, it is another nice supporting mod, but you will gain more from the tuner or converter. Big plus to the throttle body is that it is only a 5-10 minute install.
