The Vortech S-trim kit comes with everything you need: head unit, bypass valve system, T-Rex pump, FMU, MSD boost retard box, brackets, lines, hoses, fittings, clamps, etc. You will however need to switch to Mass Air. The S-trim kit was designed to bolt right on to a stock 5.0L engine (mass air) with nothing else to buy.

If you don't change the pulley on the S-trim (smaller pulley to make more boost), then you don't necessarily have to get a bigger fuel pump or bigger injectors. The kit comes with a T-Rex inline booster pump and an FMU (fuel management unit), so your stock in-tank pump and 19# injectors will do. But if you have a better intake manifold, heads, exhaust, cam, etc. then you really should upgrade the fuel pump and injectors.

The other stuff already mentioned is good: one step colder plugs, smaller plug gap, only run 93 octane or better gas, take your timing back to stock (10* BTDC), etc. The MSD6AL box is a nice addition.
