If you've got any experience at the unix command line you can start the Terminal application in "Applications / Utilities" folder and have full access to ps / top / grep / etc that you would have on a unixy system.
As others have said that "wheel selector deal" is probably the dock -- a bunch of icons in a single row, with a smiling square at one end and a trash can on the other. Running programs have either a glowing dot or an arrow next to them. You can also see what's currently running by pressing Cmd+Tab (just like alt+tab on windows) -- the Cmd is the button to the left of the space bar and next to the Alt/Option key, it has a clover curly thing and on old models (ie, Powerbooks) an Apple icon as well.
