Good advice so far, except it is usually considered bad form to adjust a
calibrated monitor to "match" a print. By definition, that will leave it
"uncalibrated" for other images. (not good advice)

That depends on how you set up the general Settings and RGB spaces under
Preferences. If you select US Prepress, correctamundo.

No. Inkjets do not have a "working color space", rather they each have
their own device dependant colorspace, the gamut of which is almost
invariably larger than sRGB, and in the case of 7 color inkjets, much
larger.

This is a commom misconception. For all practical purposes (unless you're
nitpicking with certain uncommon shades of saturated cyans), the choice of
RGB working space has no impact on color matching the screen with inkjets,
irrespective of whether or not you use PS or the driver to manage color.
Mismatches generally occur as a result of using a bad monitor (worn out CRT,
or most LCD's), poor monitor calibration, poor profiles, or crappy driver
color management. Take your pick, but the file color space isn't the
problem.
The fact that OS's and some mini-lab machines (notably Fuji and Noritsu) are
incapable of reading profiles, and thus are set up to "assume" sRGB is
indeed regrettable, but that does not mean that the "rest of the world" uses
it. Using sRGB with a modern inkjet is like putting regular octane gas in a
porsche turbo. Sure, it'll run...but why would you do that intentionally?
(especially when you already have the tools right in front of you)
