This got a little longer than intended. Thank you for your patience in reading and any replies you can make!
I've never owned or used a cell phone, let alone a smartphone. The reason for this is a disability I have (C5/C6 spinal cord injury) where I cannot use my fingers. Therapists and other medical professionals describe my hands as "clawed". That gives a wrong mental image of how my hands look. Saying they are "fists" gives an exact mental image. 
Recently I've been very intrigued by Android devices with their large-ish touchscreens and integrated speech recognition/voice commands(2.1). Looking at videos of the touchscreen leads me to think I can touch or type when needed using the middle knuckle of my little finger. I can manage this on my computer's keyboard even though I have no tactile feedback from my hands.
I've used and programmed computers in my home for over 30 years. I'm not completely adverse to writing an app or two if I need to but I don't want to reinvent the wheel. 
If I do buy one of these devices I plan on using it either hanging from my neck with a lanyard or lying on a table or desk. Also it would be used in speaker phone mode 100% of the time.
These questions are for both Verizon Droids. Some of them should be answered from the user manuals but weren't.
Can the lock screen be disabled?
When the Droid goes to sleep, after x minutes of inactivity, can it be awakened by touching the screen? If no, can an app add that capability?
When a call arrives does the screen display a button to answer by speaker phone?
Can the phone feature be set to default to speaker phone?
Are the tools the Droids use to make and answer calls simply apps that can be changed via the market? If yes are there many alternatives?
Are sounds from phone, ear piece and speaker, music, ringing etc adjustable by an on-screen volume control? Does it take much pressure to use the volume buttons on the Droids?
On the Eris do the 2 hardware keys on the front require much pressure to activate? Same question about the Moto's power and camera buttons. When I'm asking about pressure needed to work these hardware buttons I'm thinking they might be similar to buttons on an average TV remote. And yes I won't really know until I do a hands on.
Do the Home, Menu, Back, and Search touch buttons require more pressure to use than the touchscreen in general?
The Eris has a home screen 7 screens wide. While the Moto manual shows only 3. Can more screens be added to the Moto?
I've read that Moto uses the standard Android UI while the Eris uses SenseUI. Can a UI be changed by a user through the market or other download?
Is there a web site I can visit with my PC that will show ALL current apps in the Market with their descriptions and cost?
One final question: Does anyone know if any new "real soon now" Android phone is coming with a larger screen?
Thank you for your time and any feedback!
