Not sure about that particular issue, but I can help with a couple of your other questions:
Fn (bottom left key) + Backspace = Del.
Apple + [ = Go back
Apple + W = Close window
If you go into System Preferences and choose Dashboard preferences, you can redefine those F11 and F12 ones, and add in preferences for Expose etc. (Expose is a wicked little tool which instantly shows you every open window, or every window for the current application, or shoves all windows to the side temporarily to show the desktop.)
You can use your external drive but OSX will only read NTFS, not write to it. You have two choices: either reformat it as FAT (with FAT's limitations) or reformat it as HFS+. Then you have to get round your PC not being able to read it, but there is a brilliant program called MacDrive which you install on your PC, which enables Windows to read and write to HFS+ disks. I think it's about £40.
