I know what you mean, i haven't done the spring seats as mine is pretty low on the front, tbh get a garage to fit them, suspension is a right pain and its a very tight fit on Audis, that is to say your not a mechanic, if you are knock yourself out.
PM me your email address, i have a fitment guide for the ambient lighting, machine polish is easy, plenty of water and patience.
The clocks come out VERy easy, remove the plastic trim that sits underneath them but above the steering wheel, there is a screw in each bottom corner, remove these and the unit should just slide out, disconnect the harness and take it inside, there are just a few screws holding it all together then your in.
Let me know how you get on with the phone kit as i have this but dont use it, i think its just 2 screws but then you are left with 2 holes.
Chips away can plug them for you but not the cheapest.
