1)This might help with some of your questions. It's an "interactive" demo of the Sprint Touch. It shows many of the screens you were looking for.

2) To call someone that is not in your Quick Dial, you would press the green hard button, then start spelling the person's name (Xt9 style) the Smart Dial will bring up a list of contacts that have that spelling. Highlight the one you want and press the hard green key again. Pretty simple and fast.
3) Yes. Thankfully unlike Palm the screen shutdown button is separate from the Hang up button, so you can hit "Dial" and immediately hit the power button on the top to turn off the screen while you talk.
4)With the Sprint Touch (Vogue) you get 256MB of internal stoarge. You also get 128MB of RAM. I've had up to 14 programs running simultainously without any slowdown. Battery is also great!
Hope this helps!
