Find out what gear ratio you're running now. It's not true that you don't need to regear for 33s. It's not 100% necessary but you lose a lot of power and you can pretty much rule out any highway driving. I'm running 33s on 3.55 stock gearing now and it's like driving a 4 cyl and I can drive about 65 max on the highway if it's flat. You could always find look in JYs and see if you can't find a couple XJ axles with 4.10 gears to swap in since they're bolt in anyway.

TC drop is kinda pointless unless you don't care about ground clearance. Odds of it doing all that much to help driveline vibes at that height aren't all that great and you're still going to have bad driveline angles. Over 4.5" I'd definitely get an SYE even if it's just a hack and tap kit.

You're going to spend far more than you need to unless you just want the look of that much height or want to run 33-35s without modifying the fenders and stock flares at all.
And what exactly about that indicated that he needed to cut anything?

First you need to figure out what transfer case you have. Does your 4x4 shifter have a "Full Time" option or not? If it does you have an NP242 and there's very few options. If it doesn't you have an NP231 which gives you quite a few.

I had a 4.5 inch kit on my old jeep and 33s, and it wasn't regeared and did about 80 on the highway but it was a 01 xj limited. Do I get both items in the link I posted above?

The transfer case is shot in it so I have to get a new one, but the old one had a full time option.

The Skyjacker one is the full kit. The $30 one isn't an SYE, it's just the transfer case yoke if you need to replace it. You wouldn't need the $30 piece.

Ok cool deal. And the sye helps take out "death wobble"/vibrations?

To remove your stock driveshaft you have to undo 4 7mm bolts on the pinion yoke of the axle. After that the yoke on the TC side simply slips in and out from the factory unlike the pinion yoke which bolts on. The higher you lift your Jeep the further apart your TC and axle become. The axle side is bolted on so the slip yoke pulls further and further out which can lead to driveline vibrations. Over 4.5" you're almost guaranteed to have driveline issues without an SYE.

Iirc you can't even use the stock or stock style rear driveshaft at 6.5" but don't quote me on that. I think you have to end up getting a CV driveshaft so it doesn't bind up.

What is a CV drive shaft? Would the front drive shaft need to be extended as well?

This is for Wranglers but our driveline is essentially the same as a TJs so this should answer any questions you'd have.

I can do 80 on the highway on 34s and stock gears.

You can use 3.55's on the road and for real light off road. But what motor is saying is that they're not economical, mpg stinks, the engine/trans will be working harder than it should. 4.10's are sweet for 33's.
There's a wing nut here in town with an xj he licked up the axles and runs 35/12.50's on 3.55's, he gets stuck all of the time and gets 8 MPG in town. Yes he can still do 80. But it takes 2 years to get there and over heats.

And I guess that ibjeepin wheels lightly.
I only wheel lightly but compared to him but I works fine for now. And the guy on naxja with 40s on 3.55 only web wheels.
