Oil and battery I wouldn't worry about. Clutch pedal could be damage to the slave/master via shock from the crash, but again I'm not convinced I'd do anything to investigate if everything else seems okay.
What I would do is be very concerned about the chassis being straight, but that's something you'll only find out after you've got everything fixed and tried to do an alignment. If you feel like it, it might be a good idea to post up exactly what you have to replace and the costs involved to give others an idea of repair costs should they find themselves in a similar place, or at least they could help determine whether someone felt like taking up trackday insurance for their own trip.
Massive commiserations btw, and I genuinely mean that: Tbh, there but for the grace of God go I. I've been lucky so far, but luck doesn't last forever. Just glad you're okay mate, that's the main thing.
