You don't have to go through any of this to put a dropped chain back on! You have to think quickly to do this, but it's second nature to me now. As soon as you feel the chain slip, you put your bike in the big ring and keep pedaling. The chain goes back on by itself. Really.
If you are on a steep hill, this might be hard, but you can carefully shift the chain down to the next lower ring as you keep pedaling once it's back on, but you have to soft pedal. The trick to steep grades is to put your bike in the granny gear (or small ring if you have a double) before you start the climb and put the cogs in a higher gear, so you can shift down as you need to.
You can put a dropped chain back on if you are off of the bike the same way. Put the bike in the big gear, pick it up and rotate the pedals by hand until the chain pops back on.
I do not like those steep climbs with a stop sign at the top, either.
Clipless pedals are not that scary. Make sure you have the tension set at the easiest setting, if you have spd pedals. All this talk of 11 falls is crazy. I never fell and as I said earlier, I am not that coordinated.
