Sorry for brining this up after so long. Just wanted to share that I finally changed it myself last week.
Got the CV joint and boot/gator kit from JandR. Spoke to them on phone and gave them reg. Price was good at about £25. Delivery was excellent.
Was quite easy, if you can get hold of a good club hammer, a breaker bar and the correct sockets (21mm for lug nuts, 30mm for hub nut and 17mm for removing calliper)
This is a good video:

Replacing CV Joint Boot On A Nissan Micra (2nd generation, 1992-2002)
There's one tip which i found elsewhere which is very useful, and that's to measure how far in the axle should go into the CV joint before you remove the old one; otherwise, you will be left in doubt whether or not you have tapped it in far enough. Also, you can tell if it has clicked in properly or if the pin has twisted, etc., by checking if it is rotating freely and smoothly when you move it around by hand.
Also, the ninth post down on this thread has some good detailed instructions:
