gcc compiles your source code so that the OS can understand what to do with it.

The best thing to do is to get the Mac OS X Developer Tools cd and 
install it.  It should have come with the OS when you bought it.  You 
*did* buy it, didn't you?

There is tons of stuff from the GNU people at gnuosx.org .  Apple 
also has a pretty good selection of free stuff available at 
http://macosx,com/downloads.

Yes.

The question you ask is way too broad. RTFM and, if you have 
questions based on something you have done, come back and ask 
specific questions.
