Replacing Rear Coils on a Forte

[GTHOXR8]

I've read through a service manual on how to change the rear coils on a Forte with beam rear axle (standard). I am putting XR coils in so as to lower it just a touch.

There seems to be more to it than I thought: Along with disconnecting the lower shock absorber bolts, you also have to work on the upper and lower suspension arms, remove the bracket for the stabilizer bar, disconnect the track bar , disconnect the axle breather tube.

Before I embark on all this, can anybody provide any useful tips?
Any help will be greatly appreciated.
