Upgrading a 5.3

[comicaltatertot]

So I have a 2005 GMC Sierra 1500 4x4, it has the 5.3 L33 version. It is my daily driver and I tow/haul in the summer quite often but not so much in the winter. So I didn't want to do anything too extreme. But after some research this is what I have come up with.
Vinci cam "Butt Kicker" @.050 210*/218*, .551/.551 lift, and a 114* LSA.
Dual Valve spring complete kit, 1.6 Yella Terra roller rocker arms, chrome molly pushrods, LS6 ported oil pump, LS2 timing chain and of course a dyno tune to get it all running right. Then I am rebuilding the 4L60 with a 1650 stall. Then a few months later on getting a 3" exhaust.
What do ya'll think? Would there be anything that you do differently? I am open to opinions thanks for your help.
