Then again, I don't know if there's any sort of calibration needed as part of a TPS installation, so it may be FPR (easiest), TPS (medium), and Intake manifold gaskets (hardest).

Unless you already planned to do all three replacements anyway, I'm always a fan of trying easiest to hardest with the hopes that one of the easier replacements will solve the issue.
might sound stupid but where/what is the throttle position sensor? i thought the fuel pressure regulator was pretty easy
