On the "good-tutorials.com" site, use their SEARCH button,..and write eg :
GLASS or MAC (just simple words)
Then you will get some pretty good tutorials on how to make buttons in the well known MAC/Glass transparent styles

(usually in the shape of pills and ovals)
Another one :
look in Patterns and textures for "TV-lines" (also very much used by us, hehe, and also for wallpapers for pc).
These lines create the TV-screen look
