Firearms cleaning/storage and ammo storage.....

Howdy folks. I know this may seem like a silly question concerning I have owned guns for about 2 years now. But my question concerns the proper cleaning and storage of firearms. I own the usual cleaning supplies (oil, solvent, patches, brush, etc). But I would like to get your opinions on the proper cleaning and storage of firearms. Here is a list of what I have (I don’t know if the methods are different on each type of gun)….
Glock 26
Taurus 24/7
Ruger P95
Mossberg 500 12ga
Ruger 10-22
WASR AK-47

Basically I just need to know things like where to use solvent and where not to use it, how often should I clean the guns even when they have not been shot recently, and good tips on storage. Just a good rundown on how to properly clean them when they have and have not been shot.

Also, would it be a good idea that after so many rounds fired through a firearm (of course after several thousands of rounds or so) to have you firearms looked over by a qualified gunsmith for ware and repair?

Also, I own a lot of ammo of various calibers in which I keep stored in surplus military ammo cans. Basically the ammo just sits loosely or in boxes inside the cans. (Here is the dumb question) So can ammo “expire” or over time not be any good to shoot? What are some good tips of the storage of ammo?

I know these questions may seem stupid to yall, especially since this is probably common knowledge among gun owners. I just want to make sure I am doing things right so I can get the most life and dependability out of my firearms and ammo.

Thanks for any and all information.
