There is a special 'tool' for removing propshaft bolts - it consists of an elongated and thin walled 9/16" socket. I'd done a few before I got use of one of these and couldn't believe how much easier it was.... I then bought one and haven't looked back!
You can buy them here:

(not essential but does make life easier)
As for changing the UJ's, like what the others said... only tip is lots of grease (helps hold the rollers in) and once you have one cap out it can be used to help push the others out - a suitable sized socket does the same job (maybe a bit better as you can use a smaller one and it won't get stuck!). Also the last one I did required quite a lot of 'persuasion' to get moving - just be gentle with the new UJ!
This is not a witty signature
