Just an update, I managed to return the LHD lights as the seller wasn't aware there was a difference between LHD and RHD lights!
Bought some more projectors, light is much better than the original headlights. I also wired in the 'halo' to the sidelight and disconnected the sidelight bulb so it displays only the rings. Admittedly, the rings are not very bright (fine in the dark, but then the full lights are normally on).
I also had the missing bracket problem for my washers, tie-straps work for now until I find something better.
I would like to do the full xenon retrofit at some point, but am unsure what exactly is required?
Obviously headlamps, ballasts, front and rear levelling sensors, wiring.
If the parts were sourced, is it a matter of plug and play (plus STAR) or more complicated?
