These are good, might I also recommend Alex Maloney's course with audio lecture recordings

*UPDATE*
Giovanni Gallovoti written a clear, free online, "advanced" text on mechanics filled with clarity and exercises.

http://ipparco.roma1.infn.it/pagine/deposito/2007/elements.pdf

Note: This book is NOT as advanced as Marsden or Arnold, but it is more advanced than Goldstein or Jose/Saletan. Read it, you will not be disappointed.

*UPDATE*
Andrew Lewis: Lagrangian Mechanics, Dynamics, and Control (http://www.mast.queensu.ca/~andrew/teaching/math439/notes.shtml)

A VERY rigorous mathematical treatment of Lagrangian Mechanics. You should also read it if you want an axiomatic knowledge of Newtonian Mechanics and Galilean Spacetime.
