In case you have not already come across it...

rpmbuild -bp package.spec

       -bp    Executes the "%prep" stage from the  spec  file.  Normally  this
              involves unpacking the sources and applying any patches.

After you make your patch(es) [and put the patches in the SOURCES dir, with appropriate changes to
the spec file], you will probably want to build an SRPM [ -bs ] then clean out/change your %_topdir,
install the srpm and make sure it builds as expected. [if you had found the -bs command, made mods
and tried to continue on with building using rpmbuild you might be a bit frustrated about now,
because rpmbuild always starts from the SOURCES dir and spec.]

the following seems like a good place for you to start setting up your environment, for the kind of
work you are proposing:

If you want to follow all the fedora rules, then you should probably start setting up your
environment IAW:

Hope you find this helpful.
