One thing I noticed: the lab processed neg strip doesn't appear to have any orange film base in your image. Do these negs really look like what I see here on my (non calibrated) laptop monitor?

My first reaction when I saw what you posted was that the "lab processed" negatives looked to be more screwed up than the ones you processed.
But then, I don't shoot Fuji, so I could be wrong.
EDIT: One further point - the "orange" mask is integral to the film, and serves to essentially correct for the inherent limitations of the colour dyes in the film.
It is a good thing, and it is automatically adjusted for when the negative is:
1) printed optically on to RA4 paper at normal filtration settings; and
2) scanned on an appropriately calibrated scanner, used with appropriately configured scanning software.
The "automatic" settings built into most scanning software: yech!
