Lose the shorties - get longtubes or midlength headers.
Do a search on that stuff, there's a ridiculous amount of information on here about it.

Lose the handheld programmer and get a tune from Nelson Performance (or similar).
Do a search on tunes, there's a ridiculous amount of information on here about it.

There are lots of converter companies. A 2,600 converter would be about right.

A shift kit isn't going to "distroy" your tranny and there are only a couple of major brands.

Oh, and do a search for every keyword you have a question about it. If you can't find an answer on this site it either doesn't exist or you didn't look hard enough.

Most people on here have Transgo's Hd-2 shift kit, but i have the SK 4L60 E kit, which is the step down from the HD-2.

I really like mine, it shifts nice and easy normally, but at WOT it chirps the tires and slams some gears

 

What year is your 5.3?
The Transgo HD-2 shift kit and Corvette servo mod will 'reprogram' your transmission to shift fast and cleanly. You will have no issue with your superchips as long as you have line pressure set to stock.
As far as torque converters go there are two favorites on this forum. Yank and PI. Both Yank and PI offer well built converters.
What else do you plan on doing to your truck? You want a stall rpm set to match your rig so if yoou might do a cam later you'll need to consider that in your purchase.
There is a lot of great info here on this site, if you want to save some big $$ i advise you take the advice above and read as much as you can, and ask a lot of questions.
