Thanks very much for the helpful reply. Part of the problem is that I'm unfamiliar enough with using profiles that I also used the wrong terminology in describing what I had done. I obtained the profiles from Dry Creek and actually followed their instructions in the "using Frontier/Noritsu profiles" tutorial very closely.
I think the info you had on the bottom, which indicated that the lack of an embedded profile can result in what looks like an oversaturated image was the info I was looking for. Sounds like I did the right thing and this is simply what you see within Photoshop when an image with no embedded profile is viewed. i suspected as much, but wasn't sure.
The images are at Costco now, so we'll see how they turn out. My first batch was simply awesome (and for whatever reason I didn't notice this same issue).
Thanks again for the very helpful guidance.

If you assigned the printer profile, your images have problems.In a rudimentary fashion, yes. I've been printing to at least a
couple of different photo inkjets previously and the monitor color
has been dead on relative to both printers. Thus, it's my
assumption that I'm not far off the mark there. What I'm seeing on
the images that I assigned to the profiles is much different --
basically the colors (particularly green) seem way oversaturated.
If I reduce the saturation of the image, it looks better and may
submit the prints to Costco after having done that.
You assign a profile when the image is tagged with a color space
you know is ncorrect. In your case, I expect you are editing in
sRGB, Adobe RGB, or another common color space. If you assign the
Costco profile, you are saying "my camera shoots in Costco 123
color space"
What you want to do instead is convert your images to the lab
profile. This changes the actual image data to compensate for how
the printer lays color down on paper, rather than simply re-tagging
the file. At this point you should save the image without an
embedded profile. Profiles add to the file size and are ignored by
the printer in any event.
If you then reopen the files without telling Photoshop what color
space they are actually in, PS guesses and assigns your default
working space. This will be a larger color space than the printer
color space. The result is that saturated colors in the file
appear hyper-saturated on screen.
