To follow up and answer my own question.... Apparently my button just happened to pick this moment to fail on it's own. I very much doubt I did anything to cause the failure. I disassembled the whole thing so I could get to the sleep/wake button. The mechanical (clicky) action of the switch is built into the electronic switch itself. It is not part of the physical sleep/wake button on the outside of the phone. Nor is it something that you'll be able to realign or set. That is to say, the clicky action is part of the tiny switch that is attached to the Audio Control Cable assembly along with the volume buttons that have the same clicky action, and the mute switch . The action is created by a raised dimple of steel that springs in/out when pressed/released. The result of this being that if your button works but no longer springs back, you still need to replace the button (that is, all the buttons!).
Argh!! Don’t put the suction cup over the home button to pull. While it works, it also breaks the screen at the weak point below the home button. Ask me how I know.
There is a black plastic trim ring on the front of the screen, on top of the digitizer. While not technically required to it does provide a barrier to crud getting under the edges of the screen and also looks better. It is stuck down with adhesive or double sided tape. You can slowly and gently pry it up from the digitizer, remove the old adhesive and re-stick it down with double-sided scotch tape on the new digitizer. This is possible to do after you have everything re-assembled but is much easier to do BEFORE you reassemble. Just align it to the inside edges of the screen.
