In Terminal, if I hit tab twice, Terminal asks if I want to list all 1580 possibilities. What is this, and what is this used for?

You may use iTerm2 and just select in preferences to "reuse previous tab's directory"
You need to, in the window you want to move, go to View-> Show Tab Bar (if the tab bar isn't showing already).
Then, drag the tab of the window you want to move onto the window you want to move it to.
Update for iTerm 2: In iTerm 2 the setting is no longer exposed in the View menu. Go to iTerm > Preferences > Appearance > Tabs and check "Show tab bar even when there is only one tab". Note that in early releases of iTerm 2 the setting was "Hide tab bar when there is only one tab".

Pressing 'Tab' in terminal autocompletes commands and/or paths. Pressing it twice while there are no any part of any command/path is entered proposes to you to show all possible commands.
