Future JK owner with some questions!

Hey guys, I am going to be looking at selling/trading my beloved king ranch f350 for a JKU. I have been itching to get into the offroad world and the weather in Florida has been too nice to have fixed doors and roof! I am coming from the full size truck world and don't know as much with jeeps, here are a few we questions I have.
First, I want my JK to have some size to it as well as off road capability. If I can find a decent rubicon with low miles for the right price I will do that but it looks like I will have to get one with a d30, what kind of tire size and off roading can the d30 take? I don't want to spend aton of money beefing it before I get a 44.

Second, I plan on a 3-4" lift and I've been reading a lot about it but still can decide, what are your personal experiences ( not looking to spend more than $1000-1500 on lift itself ). Also lets say I do a 3 or 4" on 35s/37s, what all will I need drive train wise to make this work properly? ( such as SYE, Driveshafts, what gears and are they necessary right away? )

Third, if I did get a Jk with a 30 and want to go up to a 44 is all I need the axle or are there other parts and pieces?

Fourth, I have seen some jeeps that will literally be 3-5k cheaper because they are 2wd, which isn't a surprise but how much would it really be if I bought the parts used to make it a 4wd with a 44? If im going to have to buy a 44 anyway...? I'm not sure just a crazy idea, I'm comfortable doing all the work my self just need a tcase w/ adapter, drive shaft and an axle right? Thanks guys

I don't think you mentioned what year. I would go with the 2012+ that have the 3.6L engine as opposed to the 3.8L. You'll thank me later.

I was looking at the 3.8s, the only negative over the 3.8-3.6 decision was the 3.8s will burn some oil

3.6 is more fuel efficient, and way more powerful.....
I wouldn't personally fit anything bigger than 35's on a D30 front.
How long a D30 will last depends totally on how you drive it.....if you drive like some guys I see on youtube and think you have to crash through everything at speed, you'll kill the D30. If you're careful, it could last you for years.....and it depends where you go and what you expect to do.....go jumping rocks and ledges, and you'll risk damaging it far faster than regular trails and beach runs.

Don't buy the 2WD JK's!

I'd stick to 35's if you get a D30.

Minimal lift, go with 2.5" of lift, that will be fine for 35's.
I'm running 2.5" & flat fenders and have 37's fitted.

The 3.8 is a fine engine, and a little oil burning is normal and expected. The 3.6 is better, I'll admit.

If you get the 3.8 and 35's, for gears: Manual-4.88's. Auto-5.13's.
