b) I don't think you need to regenerate the QSYS stuff. It's during synthesis when Quartus checks for a license, and if there isn't one, inserts this OCP logic. It's not done in the source(i.e. the QSYS generated code). My experience is I've seen this added, and as soon as we had a license we recompiled and it was gone.
