They will swap over directly. The only thing you will need to do is add switches and relays to operate the lockers. You can upgrade the factory switch panel and wire harness then get a dealer flash for stock operation though most people just run their own switches so they aren't limited to 4 low use.

Front and rear ratio must be the same or things will go boom when put in 4X4. Have the front geared to match and you'll be all good.

You can probably get a stouter aftermarket unit for about the same price. Alternatively, if you can get a used Rubicon axle for a decent price, then that would be the way to go.

I will buy the dana44 rubicon axle for the front just not right now, cant afford to buy both at the same time.
If i put the dana44 rubi. axle on the rear first without using 4x4 i'll be fine?
And is the front direct swap also?

Buy aftermarket - go for a Dynatrac ProRock 44. May cost about $1000 more in the end but it is a better axle assembly.

Yes and yes. Again, you'll need wiring and what not for the lockers, but it will bolt right in.

I have a Dynatrac axle available for sale at a discounted price. Much stronger than a Rubicon axle. Bolts right in and also corrects for caster after lifting, which the Rubicon axle doesn't do.

The link is in my signature. PM if interested.

What part of the rear diff. did you break?
You can put an ARB locker and 35 spline shafts in your current housing and end up with a rear axle that is better than the Rubicon axle. My rear axle build cost about $2k without labor and is described in my thread below.

Or he can save a a few hundred dollars and go with a Yukon Zip locker, which is an air locker very similar to the ARB.

Personally, I would not install an axle with an incorrect ratio on my Jeep. Essentially, you are making it a two wheel drive. If you do have to do it for whatever reason, then I think you can leave the front drive shaft safely removed, that way there is no possibility of forgetting and putting it four wheel drive and tearing everything up.
