I need to change front rotors and pads so I'm thinking about doing the back at the same time.  Do the rear rotors come off the same way as the front rotors or are they more complex due to the drive shafts?

Just the same afaik

Correct, same front & rear, remove 2 x 17mm caliper bolts, slide off caliper, then tap off rotor. Some rotors are quite tight, rears especially, there are two little (M8 - I think) threaded holes adjacent each other to screw in a bolt & press them off if they are too tight.

When re-fitting fronts, before you push the pistons back to allow re-assembly, be sure to open the bleed screw first, and drain fluid into a cup or similar.
That way you won't push crap back into the circuit that could stuff up your M/C or ABS passages if you have ABS.
 
The rears are different in that because of the handbrake mechanism, you can't just push the piston back for it to all go back together.
You will need to wind the piston back with a special tool.  When assembled a couple of handbrake lever pulls will automatically reset the proper rotor/pad clearance.
Anyway, probably also a good idea to change to new brake fluid afterwards.
 

Thanks for the info, I'll give it a try and let you know how I go
