OK, I'll stab at #3.
I used a wiegand keypad outside hooked to the wiegand (prox) reader input of an Elk keypad inside. I happened to setup the Elk so the correct outside code opened the door and also disarmed the system, but you could separate those functions by how you setup the Elk configuration.
For the main lock, you use a regular lockset and an electric strike powered by a relay. This can be output 3 or a relay like the Elk-912 hooked to any output, including the output on the indoor Elk keypad. With this setup, you just use the handle to leave. If the power fails, use the key to enter.
Can't speak from experience on the deadbolt, but once you've located an appropriate electrically controlled one, you can do pretty much whatever you'd like with the Elk.
See my "calculator" page to help setup the wiegand user id for the Elk and for a link to the outdoor keypad I used. The strike I used was from RCI
