i agree with mr48chev on the brake switch and applaud his artwork
don't loctite the shift linkage or anything you may need to adjust, ever. it looks like you have lock nuts on the linkage. especially if your column is still held in place with wood shims.
properly designed, the steering u-joints and shaft can't fall out with all the set screws removed. that said lockem down tight with lock nuts, assuming the wood shims are gone. not that i see any u-joints in your pics.
shocks: download the monroe shock absorber catalog and look at what they offer for lengths and ends. you may end up moving your x-member forward a bit. figure the length of sitting on the bumpstops, to airborn, for the max/min length. you don't want shocks bottoming out before your bump stops, things will break
