I recently got a copy of Cubase SX in the hopes of being able to do some recording.....only one problem, I don't have a ****ing clue how to use Cubase lol. Anyone got any quick hints on how to do any of the following?

Change the speed of the click
Record Midi drums
Record guitar through my Line6 Tone Port

or, if any one knows of a decent online tutorial/guide, could u set me up the link?
