Default 4t60E rebuild kits suggestions

The engine is complete! So EchoSSEI (Bob) convinced me that before I drop it in, I might as well rebuild the transmission in since it has more than 200k miles on it and since I am 7 bolts and 2 drive shafts away from pulling it out. Plus I don't know how all the performance parts on the motor will affect the tranny lifespan in the next few months. I've been doing some really cursory research on how to tackle it and could use some feedback.

I went ahead and purchased that DVD of the 4t65E performance rebuild floating around on eBay and it claims, in addition to a general overhaul:

Quote:
*Install process of a valve body shift kit
*different chain options
*how-to modify the hydraulic apply circuits
*different horsepower ratings for different clutch packs
*supply more oil to the support bushings
*proper clutch pack preparation
*how-to modify the drum apply area for a better grip
*tips and tricks in order to run cooler, shift faster/harder/firmer, reduce shift overlap, increase line pressure rise
First question: How much of this does not apply to the 4t60E?

Secondly, I want to purchase a rebuild kit (as my title suggests). I found a few on eBay. Assuming a fairly tight budget, should I get one with pistons ($275) or without pistons ($136)? It seems like both kits contain borg-warner frictions and steels. However, these kits won't help me out very much on the above stuff I have quoted from the performance rebuild DVD.. Am I right about that? (Don't know much about transmissions or parts vocabulary but I'll definitely be learning from this project). Is there a better kit out there I should get? Should I be looking at 65E kits too and piecemealing parts from two kits?

Thanks for the input everybody

Additionally, if I decide to swap it out for a 4t65E, what would I have to replace aside from the PCM and the wiring harness?
