Good icon text tutorial

Hey everyone. I've been wondering about this for awhile and now i'm planning to work on making alot more graphics I need to figure it out.

I usually only ever use text brushes, as any text I do on icons never shows up clearly. Never good like a brush. Is there any good tutorials about adding text (only short words really) to icons? I have alot of fonts, I dont need a font guide, I need a general one for adding on to icons. Checked the memorys but nothing seems to fit with what I want. Oh, and what is "tracking"?

I use photoshop.

Examples.
