Finally... she's back on the road. In the last week I've shot blasted the control arms (which were in quite a bad way), plus the plates around the rear subrame mounts, drilled & retapped the ARB mounts, wirebrushed & painted it all.
Yesteday I got the subframe back in (with the entire exhaust system still in one piece). Today I started the engine for the first time in around a month... without issue (doesn't sound that big a deal until you remember it's been out of the car and disconnected from everything and I had to put it all back together correctly). Ran fine. With my foot on the brake I moved the autobox selector through the gears to make sure the fluid had got everywhere it needed. No leaks, so then I droppped it to the ground and went for a test drive. Shifting felt a little awkward at first, which I put down to it needing adaptation but within 3/4 of a mile the fault lights were on for both gearbox and engine

Limped home with the display showing (and it driving) like it was in 5th (in D or M) unless I selected the low range. Not good. Read the codes- just P1743 , too much slip.
Checked WIS to see if I'd missed anything (e.g. should the torque converted have beel filled with fluid before fitting) and then remembered that as a precaution, because mine is an mY03 an the donor box came from an MY06 I'd got the ECU as well. So I swapped the ECUs over. On start up there was an error code, P0725, rev disparity. Wasn't looking good. However I cleared the code and went for a drive... Bingo! All good now

So there we are, I've successfully completed the most complex procedure I've ever undertaken on a car and come away (relatively) unscathed. 4 weeks later and she lives. Yay!
What it's taught me is that most procedures are achievable for the home mechanic, but you do need to have
a) time- things will not go as well as you hoped. We are lucky to have 3 cars beween 2
b) some of the right tools e.g. engine crane, bearing press
c) the ability to take a step back and think every now and then
