Hmm ... usually in the absence of a keyboard, most Suns switch
to using a serial terminal on the TTYA port on the back. It is too
late (and I am too tired) to dig into the FEH to make sure that the 450
has the TTY ports.

Yes -- it is (almost) unique to Suns. (Solbourne made a SPARC
desktop system with the same connector, but a different pinout,
resulting in plugging either system's keyboard into the other system
result in a blown fuse. (At least, back in those days, they used bi-pin
fuses so they were easy to replace -- not the more recent surface mount
fuses.

Yes.

Pretty much any Sun keyboard with the right connector. The ones
for the Sun-2 machines used a RJ-45 connector IIRC (with a separate one
for the mouse), and the latest Suns use USB keyboards where anyone's
keyboard will work, but many don't have the special keys which make some
things easier.
There was someone offering a Sun keyboard and mouse on freecycle
(local free transfer of ownership in place of throwing things away) a
couple of days ago. Look on Craigs List, and eBay and other such places
for old Sun keyboards.

Probably -- but a *lot* more expensive than finding an old Sun
keyboard and mouse. (Be careful that a lot of the earlier mice were
optical, and required a special mouse pad.)

Yes -- the serial port and a serial terminal (or another
computer running some form of terminal emulator program). Anything
which pretends to be a VT-100 should work well, though the install
scripts offer other types of terminals as well.
Good Luck,
