I don't think you need to do it "in the background" (i.e. in a separate
thread or process). You can simply do the processing in the action
module.

Sure. Add the volume information to the add_sku page so that the admin
can enter it (naturally, you can get rid of the List Price and Sale
Price fields since the admin will no longer be using them). Then you
can do some algebra such as the following (in ADD_SKU):
function priceByVolume($volume)
{
if ($volume < 15) return 23;
if ($volume < 30) return 43;
if ($volume < 45) return 56;
...
}
$listPrice = priceByVolume($width*$height*$length);
if ($rejacketed)
{
$listPrice *= 1.1; // add 10%
}
if ($quality == "NEW")
{
$listPrice *= 1.5;
}
I'm sure you get the idea.

You probably only need some simple algebra (so far, you have not
mentioned anything more complicated), so you can use something like the
above example.
