List of thinings to do before winter.

[redeye280z]

I have a bad AOS and I am planning on changing it. While I have the car in repair mode I was planning on cleaning the throttle body and doing a tune up. I will also be flushing the cooling system and changing all the oils engine and transmission included. Basically I will do all of this before storing the car for the winter and I was wondering if anyone has any tips on what else should be done or tips on getting it all done right. I appreciate all the imput.
