Those are definitely just standard multi-layer ceramic capacitors (MLCCs). They're fine!

Ah yes!  After googling some images for tantalum and for mlcc I can see that, even though they may be similar, you can see some obvious differences.  I don't believe I have to worry about polarity with C29, C32 and C46.
CJay:
What he said, they're not polarised :)

Oh, put the links back one at a time and check to kake sure the sort doesn't raeappear (I don't think it will), the reconnect the larger board and check again.

Put the regulator back in and check, then I think you can probably power it up...

I've put the ceramic caps and the regulator back in and reconnected the boards.  So far the short has not reappeared.  Time to buy a new electrolytic cap and see what's what!
Dubbie:
Nice one.

These repair threads are always fun!
StillTrying:
I don't think there's much reason why you couldn't test it without the 100u. Connect the DMM to 0V and 12V points before applying power, and switch off quick if it's not 11.5V to 12.5V, and keep eyes and face away from the PCB just in case!
