Modding: When and how?

[bf-110]

Hello mates.
I've been developing an interest on IL2 mods but I need some help before installing them.

First is: is it better to wait until TD release their last patch for IL2 before installing mods on the game? Or people usually have one backup folder of the game and other used for mods?
If yes, when a new TD patch is released,you have to install it on the backup folder,copy it again and install the mods all over again?

Do all planes,ships and objects mods need other mods to work?

When a new version for a mod that you have comes out,can you overwrite the previous version or you need to uninstall it first?

Installing a mod that was made for a previous version of IL2 will cause crashes and bugs?


Thanks
