That lot sounds quite ambitious Alan although most of it can be accomplished with one descent to the deck and meticulous planning of what tools/parts you need to complete all the underbody jobs. That way you only have to get vertical again once at the end.

Do you have an old "office chair" on wheels? Handy for scooting between headlamps as you adjust their aim without having to bend over too much to tweak the adjuster screws.
