Remove the TB spacer. It does nothing for the 4.7L engine.
You have either a 65mm or 68mm throttle body. The size is stamped on the butterfly. You may have to remove the throttle body to see the number. If it's 65, get a 68mm throttle body.
If you're looking for a wee bit more high end power, you can replace your stock intake with a 2002 Jeep 4.7L H.O intake, P/N 53031739AD.
The Jeep H.O cams have been installed by some on this board with positive results.

Verify those part numbers: they may have changed.
There are also cam upgrades available from krcperformance.net.

Jay - what are you trying to do ? Despite your odd list of mods, I'm going to assume you are trying to gain more power. Your '01 already has the 68mm TB; its the '00 that got the 65mm. You could port it for a bit more flow, or go aftermarket.
Most of the torque increase of the whole HO package is available by swapping in the HO cams; there's more to be had there than changing the intake.
I saw a fair gain getting a custom flash for my PCM before the Superchips option was available, either way the 4.7 responds well to more spark advance. The jet chip generally gets bad reviews here.
The 4.7 also responds well to lower gearing.
Lead, follow, or get out of the way
