First off Welcome to the forum!
To run a 35" tire, you don't really need any engine mods. The most you will need is a set of gears to compensate for the increased tire size. Also you will need a tuner to calibrate your speedo for the new tires. The gears are really what will help you get back into the stock RPM range and will return your power back close to stock.
As for the lift kit, you can run anything from a 2"-3" and you can fit 35's just fine. Anything over 3" will leave your Jeep looking a little silly with the huge gap between the tire and fender.
35's are a great tire size to run for a dual purpose rig, they leave you with enough ground clearance to tackle some great trails, while leaving you pretty comfortable to drive every day on the road.
If you have any questions shoot me a PM and I can help you out!
