If you're looking for a tutorial, that means you really don't know
tcsh all that well. Since your mind is still open and impressionable
(insofar as shells are concerned), i'd suggest you use
bash. Don't waste your time learning yesterday's news.
bash shipped with Jaguar, and is now the default shell on Panther. Since it is also the shell of choice on Linux, there are lot's of on-line tutorials for bash.
IMO (strictly an opinion; no religious wars please), it is the better of the two shells, but YMMV. You can find
links for shells here, including comparisons between shells.
