I haven't forgotten your request, I promise. I'm still planning to do it, but sanami276 just published a guide to how she uses textures. She's like a million times better at this than I am so I wanted to be certain you saw hers since I doubt I'll have a third of the useful content that she managed to put together. The link to her post is:

Hope this is helpful. :)
