How to rollerize a 4l80e

I have a 1989 v3500 Chevy 4x4 square body crew cab that I swapped in a 12 valve Cummins and a stock 4l80e that was pulled from a low mileage 2003 box van. The Cummins is currently making in the neighbor hood of 400hp and 1100ft lbs of torque at a very low RPM (max torque is usually made in the 2000rpm range). I am using a TCI EZ TCU by Fast to control it.

I haven't pulled it apart yet and needless to say the stock transmission did not last. Under full throttle 1st gear pulled strong, 2nd felt like it slipped, the converter lock up was not as firm as it once was and with the converter locked the truck didn't set you back like it once did. Now its not making any line pressure after idling in the yard I want to attempt to build if right this time around. I plan to go with a tripple disk converter tuned and built for the Cummins powerband.

My main goal is dependability with crisp shifts with out being to harsh since this is often used for the occasional under 10k light towing daily driver often ran in Over drive, and I am hoping the 4l80e is capable of this.

I recently ordered a Stage 5 kit from Jakes Performance with a valve body re-calibration kit that blocks off the accumulators. I plan on using the ATRA manual for most of the rebuild.

I have a few questions before making my order I really need experienced opinions on.

1.) With my application at a Low 2000RPM making 1100 ftlbs of torque is it neccessary to rollerize the rear case bushing?

2.) On my 2003 4l80e is stock rear case lube accumulator feed that lubes the rear case bushing sufficient or is it necessary to block the accumulator feed lube tube and run a early intermediate shaft and out put shaft?

3.) My plans are to run the Sonnax Smart-Tech Overrun Clutch Valve Kit Part No. 34200-40K. Running this kit do you think my late model overrun clutch will hold up or would it be wise to swap it to a early model overrun clutch? I have heard about one high HP application that it did well using this Sonnex kit.

4.) Any addtional parts or tips would you recommend for my build that is not included in the kit?

In advance I greatly appreciate any help. Like most people I am on a budget, my trucks is more of a hobbie I enjoy tinkering with but want to build it right. I built a few transmissions in the past and feel confident I can build this one by being thorough and paying close attention to detail.

You'll likely be more apt to get a response if you ask a mod to move this to the Engine and Drivetrain section. That is where the trans experts hang out.
