Thanks, but let me ask it this way.
If I set the Photoshop 'Working Spaces' RGB setting to AdobeRGB,
and my monitor and printer are sRGB...what have I gained? Wouldn't
a working space of sRGB do just as good, maybe better because the
mapping to the monitor or printer ICC profile isn't much of a change?

Any advandages of a wider gamut like AdobeRGB would be for editing latitude of the most vivid colors. Less color clipping could occur in long sequences or during heavy editing. The posibillities of those quantization and rounding errors can be less with a wider space if you solely think about the more saturated than sRGB colors. But, it can get worse for your "inside sRGB gamut" colors since there are fewer "buckets" to hold the sRGB part of the gamut. If everything happened in 16-bit you would be safe, but even with the smallest editing in 8-bit you would be worse off with AdobeRGB than with sRGB, IMHO. For images, I think that you - as most others - are best adviced to use sRGB only. There are situations that demands a larger gamut, but most of them are outside the photgraphic world, like in creating logos, art, etc. that have a fair chance of beeing reproduced on relevant output equipment.
