If you are going to rebuild your kernel from new sources, you probably
want to update and rebuild your whole system. From the handbook:
Warning: While it is possible to update only parts of your
source tree, the only supported update procedure is to update
the entire tree and recompile both userland (i.e., all the
programs that run in user space, such as those in /bin and
/sbin) and kernel sources. Updating only part of your source
tree, only the kernel, or only userland will often result in
problems. These problems may range from compile errors to kernel
panics or data corruption.

You don't need the repository, just a snapshot of the source tree for
the version you want to build. In your case, with 4.5-RELEASE, this
would probably be the security updates using tag RELENG_4_5 or
4.5-STABLE with tag RELENG_4. In case you didn't already find them,
there standard supfiles in /usr/share/examples/cvsup/. The two files
you will usually use as an administrator are standard-supfile and
ports-supfile.

Same as above. You just need a snapshot of the sources for the version
you want to build.
A couple pointers:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/cutting-edge.html
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/cvsup.html
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/cvs-tags.html
BTW, building world on a P133 may take weeks ;-)
Good luck.
