A really good reason to not wrap the bars until after a few rides is that it makes dialing in brake lever location easy. Ride with the tools for levers and stem in your pocket. No bat tape? Stopping and moving stuff is quick and easy. I go a step further. FIrst tape jobois with cheap cloth tape, wrapped from the bar-ends to the stem. Gives me more chances to move the levers since cloth tape unwraps and rewarps nicely.

The rest of the stuff - usually I have most of the gear and not one or two important parts on hand. So order is dictated by what I have. It all works.
