I'm very pleased to read this Jonathan.

What exactly is that piping supposed to look like?
Item 14 here. I would treat yourself to Rimmer's stainless steel version to replace the non-standard plumbing you have at the moment. Whilst you're at it, check that Mr. Previous Owner hasn't by-passed the oil cooler permanently.

The temperature rises to working levels normally.
I forgot that you've only just bought this V6 so just to confirm that the gauge should reach the nine o'clock position in about a mile. Does it?

However, interior heating is nothing to write home about. It is very, very patchy, and most of the time only blowing cold air.
Ah hah! This is the classic symptom of air in the cooling system. I know that you've bled it according to Haynes but something might have gone wrong or air has entered the circuit through a undetected leak or worn expansion tank cap seals.

For your next move Jonathan I would recommend another attempt at bleeding but this time following MG Rover's procedure which I have reproduced here.
Note that the expansion tank must be raised and the bleed screw never opened whilst the engine is running.
