Hi there good to see a return to 7's from you. The doorlock probably needs the turn the ksy lift the handle trick, i.e. lift the huandle fully and then pull the button up past the resistance point to resynchronise it. If this fails then it probably the solenoid.
The shimmy can come from several sources, if the car has original wheels and they are balanced then,,,,look at the upper wishbones as No.1 then lowers as No2 then a partially binding caliper as No.3, while you are under there do a full check i=on the steering draglink arms and track control and ARB link kits.
The ownersmanuals come up regularly on ebay, I have the Bentley manual on the e32 going up for sale shortly if you need one of them and the tools again are easy pickings from fleabay.
If I can be of any further help just ask
