Major flaw here is setting your monitor profile as the RGB Working Space.
PS6 will use the monitor profile for your screen preview anyway. Better to
pick one of the "standard" RGB working spaces like ColorMatchRGB or AdobeRGB
(so help me I still like BruceRGB as a good print space).

"Preserve the embedded profile" is generally better choices here and check
ON all the other options for missing/mismatched profiles. You'll probably
get asked a bunch of questions regarding profiles when you open some of your
existing images but it's better to know what you're opening than not in my
opinion.
The "Convert to Working CMYK" would be the one I would question here the
most, more so than a "Convert to Working RGB" choice. One has to assume that
whoever converted the original image to CMYK knew what they were doing and
that a conversion to some generic working CMYK might be questionable. On the
other hand, IF I had a *custom* ICC profile from the printer I was going to
work with, then I might consider an "automatic" conversion to their
"PressCMYK" profile. In any case, I generally prefer to bring in most images
intact (this means either unmanaged or with the embedded profile intact) and
then use the much "smarter" Convert to Profile option in PS6.

Looks good, just be careful of the "Intent: Relative Colorimetric" setting.
Again, probably better to use the Convert to Profile option which gives you
the option to choose the rendering intent on an image-by-image basis.
There's no one rendering intent, in my opinion, that works for ALL images.
