Need Help With Textures

[HarmonicNodes]

Hello, I have been learning about modeling. But I am quite confused about how texturing works. 

The tennogen help area lays out the specific texture maps, Albedo, Normal, Metalness, Roughness, Emissive, Tintmasks. 

My goal is to create a syandana. I would like to have part of my syandana involve a glass flower.

 

This is a model I made in blender -->    

 

What are the steps I need to take in order to get my materials off my models and into a .png texture map format?

I have GIMP for my photo editing software. (never used it before though).

here some stuff that can help you:

PBR theory, good overview what is going on, not blender but principles remains the same:

texture painting in eevee, blender 2.8 pbr rendering in a new viewport is really good:

and, I would suggest you to look at krita, it's more "photoshop like" and more actively developed than gimp
