I smoked the board on my WD1600 drive thanks to a bad power supply. There are
tons of similar boards on eBay, but I cannot match all of the numbers.

1) How many of the numbers above have to match to get a board that will work
with this drive?
2) Is it likely that a defective board damages anything inside the drive?

As to 2), there is typically a read amplifier close to the heads and
inside the drive. You may also have ''smoked'' that. If in the literal
sense, then powering up the drive will result in a head crash with very
high probability, as smoke particles are typically larger than the
head-surface distance.

Should I buy a board and give it a shot, or am I likely to toast the replacement
board? I would really like to get the data off the drive, although it's not life
or death.

I don't think you will necessarily kill the replacement.
I just think that your chances are slim (read amplifier dead)
and that you may kill the drive heads. There is a chance that
the read amplifier shorts out some power lines and that you
will blow filters on the replacement board. I have no idea
how likely that is though, but you should probably be prepared
tho loose the replacement board too.
