When a .plt file is created, it's created as either relative (depends
where it's unpacked), plt-relataive (goes into the add-ons directory),
or plthome-reletaive (goes into the installation directory).

Yes. (Most things have to be patched here and there for a new version
anyway.)

Yes, or just open the file in DrScheme.
