When you say the drivetrain is totally shot which bits do you actually mean?
If you just mean the front chainring, they are just standard Stronglight rings. Brompton dealers do sell replacement 'Brompton' branded rings. Likewise if you need just left or right cranks, or a whole crankset. Go to sjs cycles and search for 'brompton crank'.
I have an SS model and I do have a spacer fitted between the hub and the plastic guard before the cog. I think the spacer is probably generic. Again I looked on SJS for a brompton specific spacer and nothing came back.
I take it you figured taking the shifter, cable and derailer off is pretty straight forward. The tensioner stays on as is I believe.
