Hi all, Its going to be a while before i can start my tank set up and cycling, So I just wanted to get some of the basics down

So i just have a few questions like
-What should i feed them? My tank kit came with a free sample pack of some tetra flakes?
- It gets Kinda hot here in the summer so i was wondering what could i do to cool the tank down, if need be?
-If i loose power is there anyway i can keep the water temp up? or just wait it out and hope for the best?
-Any one got any ideas where i could get TSS in the ME/NH areas?
-When i bought my air stone there were two in the pack, is there a way to use both with one pump? or is one just a replacement?
- For a water conditioner i bought Tetra AuquaSafe This is what people mean when the say treat the water with a conditioner when doing water changes, right?
Thanks for any help. Im trying to get a good idea of what im doing so i dont get all the little guys in danger
