[How order mod folders without crashing the game?]

Neither. In the launcher you can make as many "Installations" as you want. An Installation is a setting that says "launch this version with this .minecraft folder". "Version" in this case can mean any Forge version you have installed or any vanilla Minecraft version. It will then put mods, configs, worlds, etc. in the game directory you choose instead of in .minecraft.

OOOOOOOOOOOH THANKS

Use separate game directories.

 

Do I have to install minecraft in another location? or just forge? or both?

Hello, I would like to know if there is any way to classify mods inside the "mods" folder of the ".minecraft" folder. 
Because I don't like to take out all the mods that I have in version 1.7, to put all the ones that I sometimes use in 1.8
