In my search for a RX400h, which took an number of months, I recently spoke to someone in the Midlands who had one for sale. He mentioned the same type of damage to the dashboard as you describe, who knows, it could be the same vehicle (silver). I didn't bother to travel from Cornwall to view because I thought it may be difficult to repair. I hope you find a solution.
With regards to the boot issue, hopefully, as Colin states, some lubrication may sort the matter out.
I know it won't solve the issue but, if you stand to the rear of the vehicle, outstretch your hands and run your fingers down the gaps either side where the boot meets the body work. Unequal gaps would clearly indicate that the boot is off centre and might have been removed or even replaced. If the boot isn't correctly aligned, I presume it may not operate smoothly.
