OK, so I need to replace my jockey wheels - looks straight forward enough, but a quick hunt through Park's Big Blue Book and the C+/MBR collection of workshop tips doesn't reveal any guidance on the subject to confirm or deny it's simplicity.

So what blindingly obvious part of the process am I likely to completely c0ck up?

just make sure you fit the correct spacers if they are an after market replacement and the thinnest wheel is the upper one.Otherwise it's a doddle

G-pulley does the guiding and goes on the top, tension pulley goes on the bottom. Hold the mech forward when you undo and remove the bolts(do one jockey at a time) or you'll fire the old one off into the distance with the mech's tension.It's not difficult but I have seen a few wrongly assembled, make a note of where the old bits went when you remove them.

Jsut watch out for cheap CNC jockeys that have no play in them, mechs work best with a bit of play in the top jockey and I've not yet found an aftermarket replacement (even narrow ones) that shifts as well as the standard shimano one.

coffeeking - couldn't agree more.
Mind you it's all that nice Mr Shimanos' fault for slapping a patent on his floating top jockey - cunning or what!

Well tough on Mr Shimano, I picked up some cheap Tacx ones the other day!

I usually just replace like with like. Never had decent results with anything but genuine shimano ones.
