Mark,
I would replace the bearing as it would be easier and cheaper to
do now rather than after you install and it may find it bad. If
the shaft was "beat on", there MAY be little dents in the race and
you will hear ( or feel is a better term ) this as you drive.

I have never replaced the bearing on a Honda. Have done bearing
replacement on two Saturn's and a few of VW's. I guess they use
better bearings. On my 97 accord, to replace the rotor's you you
have the bearing in your hand if you take off the rotors. (see link) I
think all 90's accords are like this. I can't speak for civics.

Do you have 2 screws holding on your rotors or 4 bolts? With the 2
screw system, I think you will need to press the bearing out. On the
four bolt system as you have the spindle off, it should be easy to replace
a bearing. See link below:
