There's no reason not to use the current beta.  The current 1.7.0-68
is probably equivalent to the official 1.7.1 release.

In theory that's possible.  It's not quite clear yet if we really
want to allow it for a couple of reasons.  You read the User's Guide,
so you know that there are really a lot of changes which will also
change the user experience, for instance mount point handling, UTF-8
as default charset, to name the most important ones.

If you want to be on the safe side, install Cygwin 1.7 into another
directory, for instance C:\cygwin-1.7.

Yes.  Trouble are the user mount points.  These are the ones which under
1.5 are stored in the HKEY_CURRENT_USER registry area.  While the system
mount pointsd (the ones under HKEY_LOCAL_MACHINE) will be converted to
mount points in /etc/fstab, this won't happen for user mount points.
Every user who has user mount points will have to recover them manually
via the copy-user-registry-fstab shell script.  See the last note below
http://cygwin.com/1.7/cygwin-ug-net/using.html#mount-table

There's a 99% chance that they still work.  YMMV.
