To echo everyone else, well done for taking this on.
Standard linings are easy to come by, Howdens etc. are cheap and perfectly serviceable and they come with the door stop. All you need to know is whether it's to fit in a 4 or 5 inch wall. Get the new lining in plumb and square and fitting the doors should be straightforward.
For the shims/wedges, screwfix do bags of 100 or 200, expensive for bits of plastic but worth their weight in gold when packing things out. As you said, screw through the shims, and then if there are big gaps between wall and lining I often squirt in a bit of expanding foam to firm it all up and stop it wobbling. No need for fancy drill bits or fixings, a normal masonry drill will go through wood without any trouble and then hammer through a rawl plug on the end of a decent screw, I normally go for something like 5 x 75. If you're forced to resize the lining then that too is straightforward.
Personally I wouldn't go the route of assembling everything on the floor or out of the opening. If the door has already been cut for the hinges then offer up the door to the newly fixed lining and mark off the hinge placements to the lining. A hinge jig is a massive time saver if you've got loads to do. If the hinge placements on the doors are poorly done best fill them with a two part filler (car body filler works well if it's going to be painted) and then re cut the hinges.
For the window board, if you're going to the trouble of removing the old one, you may as well just put a new one in it's place and save yourself the time for one of the other jobs.
Excuse the essay, especially if it's all stuff you're familiar with.
HTH,
