One question, will I have to uninstall rtr before enabling that mod switch?

To get the game completely clean and ready to have both R:TR (mod switch edition) and vanilla co-exist, you will have to un-install R:TR and then either re-install or repair R:TW. You will find these as options if you choose to uninstall the game in "Add Remove Programs" (Windows XP and below) or "Programs and Features" (Windows Vista).

If I remember correctly the R:TR uninstaller is fairly messy - rather than restoring the files it overwrote in the first place, it deletes the overwrites and doesn't replace them. Repairing will only work if the version of R:TW on the CD is patched at the same version of your currently installed version (usually only in the case of the white label or gold editions). Due to this, re-installing is probably the easier option.
