Driveshaft removal questions

This might be easier, but do i need to unbolt it to remove an 8.8 axle?

Can i drop the axle, pull it out with the D/S and then unbolt it atfer i get it out from under the car?
 
I have to change out my alum. D/S for a new one this winter also, because my it was rubbing on the D/S loop and mufflers.
I read in my Haynes manual that you just make a reference mark on the D/S and rear, unbolt the 4 bolts to the rear first, drop it down, and pull the D/S out of the transmission (T-5).
Then install in the reverse order.
Is that all there is to it?
I didn't install my old alum D/S myself.
Do the u-joints, 4-bolt mounting flange, etc... come completly assembled with it?
Or do you have to use everything from your old D/S?
Thanks
