Good informative post TYT.. What you need to really think about is the gear change.. As you posted your Jeep will lose top gear forever.. and depending on the ratio of 5th gear maybe that one too.
Changing the tire circumference means a great deal to the performance of the engine. As the circumference gets bigger it takes more rpm to turn the tire. Ideally at, say 60mph, you will need MORE RPM to turn the larger tire than you now have.. So at that same speed...say 1900 rpm changing the tire size will require 2100 rpm to act the same on the street.
I'm not gonna do the math for you but you get the idea. The street is where you will feel the difference most. Off road you will have low range and 1st gear for most obsticles. But from light to light and mostly when cruising.. It won't want to go.
It is pretty easy to do the math.. just get on the hiway and see how many rpm you have now at 60mph and then do the math to see how many you will have with 35's on there.. You will find that gear is lost forever and perhaps even 5th gear..
