You will need all the parts you listed mushrooms included, as you mentioned all available from saturn

The bottom ball joint hole on the sierra upright needs reaming to accept the maxi ball joint, im assuming this is what you mean by machining

You can do this with a hand reamer from axminster tools, the same reamer is also going around members of the forum via the post, once people have used it they post it on to the next person who needs it

With regards to dampers if you can afford it go for the protech ones, i dont think they perform any better having drove my own car on gaz shocks and someone elses on protech but the build quality looks much better on the protech
