So the choices are: srgb, adobe rgb and prophoto rgb. Most of what I've read leaves me concluding that the potential improvements in printed images provided by use of adobe or prophoto are pretty much negated  by the inability to view those gamuts on my monitor. I've also heard that the photo printing/processing concerns want srgb anyway....?

Correct on both counts. I work in Adobe RGB and then convert the final JPG for print or web use to sRGB at the end of my workflow. But I keep the original PSD layered file I create as an Adobe RGB color space file to keep the full color gamut in the PSD file just in case one day it does makes a difference.

Marc, that makes sense to me. However (and I hate to even mention the name), but Ken Rockwell has quite a piece on his website which makes the point that if you cant see what you are doing (because monitor is srgb) then one may see greens more washed out (for example) on the screen than they would print from the file, and make an adjustment which looks ok on the screen, but prints incorrectly. At this point i feel a bit like the man who was just asked "have you stopped beating your wife?". To complicate matters further I emailed some of these concerns to IQ and received the following "You can save as to tiff format 8 bit RGB resulotion 300 dpi." As I am interested in fine art quality printing at A2 of anything that I would send to them, and do anything up to A4 at home, I was a little surprised at their response. I had expected 600 dpi and a bigger color space .

I just found an explanation of some of the issues around color space that seemed very helpful.  http://www.updig.org/guidelines/ph_color_spaces.html
