The front pads are fairly easy to do however due to the safety critical nature of the job if you are not a competent mechanic I would go to a garage. It may cost you a bit more but if you get the job wrong YOU WILL KILL YOUR SELF. Also remember if you do it your self you will have to give the pads time to bed in by taking the car to a empty car park and braking hard at slow speeds for about 20min.
The rear shoes are quite awkward to do so same applies as above.
Best thing to do is get a Haynes manual.
Hope this helps.
