Suppose I have a shapefile-based layer of land ownership and another shapefile-based layer of the final perimeter of a wildfire. How would you create a final reporting of a list of landowners and the number of acres each lost to the wildfire? Be as detailed as possible in listing all steps and considerations.

This is actually quite easy to do and can be done in several ways, here is a quick one:
1) Clip the parcel layer based on the outline of the fire. This will provide you with all the parcels within the burn scar.
2) Outside of the edit mode, create a new field (call it Area and make it datatype double) and calculate the area of the polygon. This can be done by this input
Dim dblArea as double
Dim pArea as IArea
Set pArea = [shape]
dblArea = pArea.area
3) Join the parcels based on land owner (one may own several parcels) and sum the area.
4) export to a report
You gave enough information and that is the quick way to do it, assuming you are using 8.x or higher.
Hope this helps
