With your temps I doubt it will ever be much over 60 even on the highest setting. As for prep pretty simple wash it out and let it air out a couple days. If you are in a rush use a light baking soda and water solution. Don't forget to add some kind of humidifier.
As for a sticky there are so many threads so many people have written a simple search should serve most people.
Good luck and welcome to the Asylum.
