Have you considered the free extension for ArcMap called X-Tools?
http://www.taigagis.com/
There appears to be some compatibility issues with ArcView 8.3. But I have
found it to have some excellent features.
It has the following feature:
Convert Shape to Centroid
This command creates a new point shape file from the center points
(centroids) of the shapes in the input shapefile. A centroid of a shape is
the spatial location of its ''center of mass''.
The command will calculate the center of any shapetype (point, line, polygon
etc.) in a feature layer and add this as a point to a new layer. It also
transfers all fields of the original feature layer to the newly created
point layer.

Subject: GISList: Constructing centroids & conflating attributes
List,
I've got a layer of polygons (buildings) with a variety of attributes (name,
address, zip, etc.). I want to create a layer that will represent each
polygon as a point feature, not necessarily as a centroid. Further, I would
want to transfer the polygon feature attributes to the corresponding new
point features. I don't see any clear implicit method to do this in ArcView
8.2. Does this require some custom code or is it a native function that I
am overlooking? Thanks in advance, and will sum.
Anthony
