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.
