I had to do the same LE vs XLE exercise for my 2001 Camry V6, and Intellichoice.com used to have full factory lists of standard equipment, options, packages, factory ordering codes, and invoice vs MSRP pricing for each one. Unfortunately they've changed their website and you can no longer access that detailed information. Lucky for me I saved the info.
This isn't quite as detailed as intellichoice used to be, but you might try this:

It's more detailed that most, but not as detailed or well-organized as intellichoice used to be. You change the model/engine via drop down menu and you'll have to compare across a couple tabs for interior, exterior, etc, but it should hopefully help you answer you question even though it will take a bit of work.
