I'm using version 2011 Build 15.4.3508.1109 but I'm sure the following applies.

1. When you look at the log-in screen, you should have a drop down box where all the e mail addresses sit; if you select the one you don't want, just above the sign in button should be a tick box for "Remember my ID and Password" and just to the right of this it says "Forget me" just click on this and that e mail address goes away.

If that isn't present on your build, suggest you upgrade

2. E mail addresses are sorted alphabetically but if you set the one you want to use to log in automatically, that should sort your problem.

3. unsure about this
