OSX keyboard shortcuts

[Paul Korntheuer]

Can someone point me in the direction of a good list of keyboard shortcuts
for OSX? I haven't found an "all-encompassing" list. I'm after simple
things, like opening the main system preferences window, and some of its
control panels.

Also, what is the method for quickly viewing what (major software) programs
are running in the background. Is there something other than the process
utility?
