Pick a direction, prioritize what you want based on smiles per dollar and work at it one goal at a time.
As far as performance, do intake/exhaust and a BB tune in my opinion. The intake and exhaust won't make as big of a difference to you until you get the tune. Once you've done those, you can decide if you want more.
Suspension, get the bilsteins since the truck needs them anyway, then decide if you want more from the various lift/level combos around the forum.
Other stuff, just make it yours work in a direction on one aspect until you're satisfied, then work on another aspect.
