I don't know how it hasn't shafted itself already with those symptoms. Yes, its almost definite that your VCU is completely buggered. That and you possibly have tyres that are not all the same make/model and pumped to the same pressure.

Get the props off before you drive any further. I would think you'll need a recon IRD as well as VCU before you put it back 4WD. That level of wind up will have seriously damaged your IRD - possibly also the rear diff.

Have you done the 1 wheel up test? I hazard a guess to say you'll have a result time of at least 4 minutes - if the lever moves at all.
 
My plan would be to do the 1 wheel up test before removing the props and before driving it any further.

If it comes back with a time over 1 minute, whip the props off - you'll need a new VCU.

Then check the oil in your IRD (drain and refill). If it comes out black, your IRD is fine. If it comes out metalicy grey - you'll need to recondition it. Remove the rear pinion and check the teeh on the crown and pinion gears - if they look excessively worn or any teeth are broken, then you might as well get a recon IRD. If the gears look OK and you know someone who's good at pulling/pushing bearings - then you can get IRD recon kits with the bearings and seals (foe about £150) I believe.

Check your tyres as above as well.
 
Do the one wheel up test asap;)
Although I suspect that the engine not going over 3K isn't related. That could be something simple like cam timing one tooth out.
