A bigger (190 lph minimum) FP won't do any harm and is recommended as a replacement for the stock 88 lph FP.
You won't see any real performance gain with this pump, it's simply a good investment.
#24 injectors won't do anything for your performance and are totally unnecessary until you dump the stock E7's and move up to better heads.
Your TB is too big for what you're running now. Your pulling in a ton of air but your heads can't take full advantage of it and a bigger FP won't help.
I believe that in your commendable quest for more performance you're going in the wrong direction here.
A few thoughts to consider:
Why invest in a new computer (unless your current one is malfunctioning)?
High-output fuel pumps and bigger injectors are installed as a necessary accessory with better heads and/or power adders.
Sub-frame connectors are an excellent investment - do that one.
I would recommend your next mod be a set of 3.73 gears and either a PRO 5.0 shifter or a shift kit (if AOD- you didn't say).
A set of headers and a decent aftermarket exhaust system (with no cats or high-flow cats if you need them for state emission laws) would be next on my list.
Then, a set of performance heads to compliment your exhaust, intake, MAF and TB, along with that high-output FP and #24 injectors. There is lots more, of course, but these are fairly basic mods that will give you big performance rewards for a reasonable cost.
Just think it through, have a plan and a goal and go from there.
