What he said.
The "cold air intakes" (laughable at best) don't give you any performance increase over the stock intake when combined with the larger fender snorkel. You'll get a lot more cabin noise with an aftermarket intake though, so if that's your thing, then there's no harm in running a filter-on-a-tube setup. Some trucks do not need custom tunes for aftermarket intake systems while others do. My recommendation is that if you do go for an aftermarket intake, drive it around a bit with the programmer and see what happens. If you run into driveability problems like surging, hesitation, detonation, etc., then look into custom tunes.
Nothing else on your list really requires custom tunes but you may want to raise the idle speed slightly to accomodate the slower drive speed of the alternator and other belt-driven accessories.
