As others have said dont start this project unless you can afford to have your car off the road and have time on your hands - I agree with them!
Firstly make sure you have a good set of tools and start with the simplest method of removal before going to presses, flame guns etc. I made up a puller system out of an old jockey wheel I had and it was perfect. I used a 10 mm dia bolt at first and while it worked in one instance the new bush was drawn in on an angle took care in getting it out again. Also stripped a few bolts. Once I used a bigger dia bolt which just fitted in the sleeve there was no problems in fact it became a breeze, just time consuming.

I used rubber grease whenever I could and that certainly made things easier for assembly of OEM bushes..
While I had the suspension out I repainted chassis, wishbones etc. Another thing I learnt was to do one side at a time so on assembly it was easy to check which way bolts went etc. This was more important for the front and I would always recommend doing the rear first as its easier.
I marked all alignment points with white out which seemed to be the right thing to do but defeated the purpose when I painted over some of them!

When I get the thing back on the road I will let you know if it has been worth it.
