Add on help

which is the exact add ons for gather mats one
where it saves the location of the resoruce node or show em all on the map

The main one would be Gathermate2.

Another useful gathering addon that works with Gathermate is FarmHud, which lets you toggle the minimap into a HUD display. It’s especially nice as you can keep your minimap off in a corner for regular play, but pop into HUD mode when your ready for serious gathering.

is that all i need

There are various addons that can work with and enhance gathermate (like FarmHud) but Gathermate alone will do what you asked for originally.
