Welcome to the Forum. The only thing I would suggest is wash correctly, and prep your paint as best as you can. Paint prep is 90% of the battle.
Between now and next week, read as much as you can in the archives, and in the detailing articles you'll find here and elsewhere.
Dave B. out host and moderator has a super book on detailing, and you can get it on this site. Until then, read, read, and read!
When you have an idea what you want to do, then ask the forum all your questions.
To start with the AIO and the SG, just follow directions included, and that will start you off in good shape. You have a good sized rig to take care of, if you start to feel that doing all this is too imposing, just do it in sections. Once you get it where you want it, it won't be much trouble keeping it there.
Again, welcome aboard, and happy detailing! Enjoy!
