A few rebuttals for your list:
1) 90% of art is spontaneous and done without thought
2) agreed H pencils are what you want to look for, and a good gum eraser
3) this is a little misleading...when drawing heads/faces it's best to start with basic shapes, usually circles and build up from there. the 'cross' is a reference for the artist when placing the face details so they are proportionally correct...i honestly don't use them very much anymore, though i'm weird
4) depends on what medium your working with, most sketch books will tell you on the cover what they are good for
5) copying someone Else's work and claiming it as your own is a nono, but copying to learn their technique, that's cool and is one way how I learned to draw characters was by freehand copying images from comic books
6) libraries are also a good way to look for ideas, or real life in itself can be inspirational
7) hand cramps, agreed, though a short 'soft' pencil is good for fleshing out shadows
8) not sure i understand what you mean, unless your stating that the object the person your drawing has only one lightsource
9) don't forget the FREE programs like gimp and PsP
Honestly your list was very vague and incomplete. I suggest editing and adding more details and some explanations into technique rather then one lined pointers.
Not sure your ready to critique work as well, but that's my opinion.
Good luck.
