2000 and 2001 are the same, I believe.
If you are sick of shifting, get the auto. It's not the smoothest unit out there partly because it has to deal with a lot of torque from the engine, but it's fairly reliable. You can install an extra tranny cooler for about $30 to give yourself an extra layer of peace of mind.
I got a front strut brace, rear sway bar, and the tranny cooler installed, and those are cheap and worthwhile upgrades.
I also have a cone intake, but it hurts the low end IMO I would put the old one back but I am too lazy. I had a modded valvebody, and while it was faster and supposedly prolonged tranny life, it shifted a lot harder from 1-2, so I sold it.
