You'll have to wait some months for FreeBSD >= 9.1.  Current release is 9.0.

I believe FreeBSD has a multisystem boot loader, BootEasy/boot0.  You can also look to GRUB:

http://www.gnu.org/software/grub 

I believe this is also included in FreeBSD ports collection.

If you run Linux, you can install LILO, which is capable of booting FreeBSD.

I believe the password files, /etc/master.passwd, are encrypted, so you can't get the password directly from that.

You would run the command passwd as root.
