Don't know which you should tackle first. I can give advise on a tip for the windlace. I installed some on my 46 last weekend. A tip I learned on this site was to cut slits in the vinal where it bolts under the trim. That way you can loosen the trim enough and slide the windlace in. Use masking tape to hold it in place while you are working on other parts, tightening, moving, loosening etc. Also before the final cutting and tightening, close the door and test the fit.
