Harrington on Hold em is definetly worth reading, especially if you're a tournament player. Its also a very beginner friendly book and easy to read.

The way you describe it, you seem to be tight weak beginner. I see no reason to play short handed. Just play full ring, people still pay you off nearly as much at these low levels and you will pay a lot less blinds. Short handed play is a not good way to start out.

"have been playing good but I often find my stash dwindling because I just dont get the cards. "

Full ring will make it less costly to wait for your cards, and at 10 NL there will still be plenty of fish to call you.
