Hello,
Can map server combine two fields and display a total for the values, or do
we need to total the values ahead of time in the shapefile?

Depends, are you talking about for labeling, expression evaluation or template
display?
For labeling: No.
For expression evaluation: Yes (using logical expressions you can do EXPRESSION
([item1] + [item2] 50)
For templates: Yes for HTML via javascript, e.g.:
script ...
var total = [item1]

Hi Mark,
Not that I'm aware of. Even if it could, I would always pre-process the
data, so MapServer doesn't have to execute those extra
