As far as effects are concerned, I still don't use that many.
The list of five(?) zeros after the note is where you put control/effects commands. For example, "C" is volume. Volume levels are 0-64, so if you have:
10C32
then you are playing instrument 1 at half volume.
-EDIT-
10000 would play instrument one at default, full volume.
-EDIT-
I don't know if that's any use to you but I'd recommend concentrating on learning how to build up a basic song first, then worry about effects later.
Just my opinion of course.
