Lvl60 max ilvl gear?

No clue what melding is. And the game does a terrible job at explaining things.

but for doh and dol, all I heat is scrips: yellow,white,red,blue... but all the relevant info is years old and some say some scripts are gone and nothing tells me what I need now or how to get it, which brings me finally here.
My question is what is the highest ilvl gear I can get for my 60 miner, where do I find it and what do I need to get it and where do I get that?

Scrips are basically just the DoH/L version of tomestones, and like tomestones, they come in severs varieties. White (level 80), Yellow (everything below 80, similar to Poetics), and Skybuilders' (used for Ishgard restoration.) Blue and Red scrips have long since been phased out and are no longer in the game.

Scrips come from turning in Collectables. If you haven't unlocked them yet, do the quest "Inscrutable Tastes" in Ishgard and the follow up quests "Go West, Craftsman" and "Arms Wide Open" in Mor Dhona and Idyllshire to get started.

Once you've turned in some collectables and earned some scrips, you can go the scrip vendor in Idyllshire or Rowena's Representative in Ishgard and buy full sets of i200 crafting and gathering gear.

Materia and melding are explained during the level 19 MSQ quest "Life, Materia and Everything". While completing the quest, information is added to Active Help that can be found under the Gear category.

It's also explained more in the level 20 DoH class quests, which hopefully you have done for GSM by now.

The game a decent job of explaining things to players when compared to other MMORPGs and the amount of information players need to learn, though there's always room for improvement. But it's outside of SE's control if players choose not to read the information they're given.
