Make Quit close the application

Question

Kinda new to my MBP w/ Lion installed.  I'm wondering if there is a setting one can chose to completely close an application when the red dot is clicked.  Right now they are still appearing to be loaded into memroy (guessing that is what is happening as the Dock shows a little white dot by the app's icon, and so you have to rt click it and choose quit. 
Also, what's the easiest ways to do screen prints, which I so often in the Windows world w/ the print screen key on the Win keyboard.  I really miss the print screen and HOME/END buttons on the Windows keyboard design.  Perhaps they are on larger MBP's as mine's a 13".
Thank you kindly in advance,
Noel

For most applications, the red dot is intended to close a window only.  That's just the way it is.
