Sneekpeekit - Printable Sketch Sheets
I recommend learning about the Visual Vocabulary from Jesse James Garrett. The website has detailed information on how to describe information architecture and interaction design. (The book is also a good read.)
Zurb has a set of responsive sketch sheets and a good article on how to use them when planning your responsive design.
Inspiration Hut also has a set of printable papers.
960grid has several printable sketch sheets; their sheets have 12 or 16 columns in them.
