Many laptops have a special funtion where the letter keys become a numeric keypad (and/or arrow pad). Refer to yuour laptop's manual (you should be able to find one online if you've lost yours) and see how to restore standard functioning.
As for the mouse, Windows allows users to set which button is the primary and secondary button. Left-handed people like it backwards from righties, you see. To change it back, go to the control panel, double click on Mouse
(you may need to click on Printers and Other Hardware
option first). Remove the checkmark from Switch Primary and Secondary Buttons
and click OK.
Let us know if that doesn't clear up your problems!Edit
: Until you fix the mouse problem, try using the right mouse button to click/double click things
