I shoot everything in RAW and Adobe RGB. When I decide to resize and save in a jpeg format, at what stage in the processing should I convert to sRGB? Before doing any other modifications, or as the last modification before saving?

My suggestion would be to make the change once you have done everything else, then want to have a sRGB JPG.
I occasionally have CNX or VNX make the color space adjustment. but mostly I rely on PhotoMechanic, as I am usually making the sRGB file for the web. I have PM change the space and resize the image, saving it as another file.
If you wish, you can have CNX do a batch process to a group of files, creating the jpg from the edited NEFs and changing the color space. Resizing is a little tricky, though, unless the images are all the same aspect ratio.

Allow me to point to a fact that as you are shooting RAW, it makes no difference what so ever whether you have aRGB or sRGB se as color profile in your camera. Color profile comes into play once you start editing your RAW file in a image editor. The camera color profile option is applicable for the in camera JPEG generation, for example if you are shooting RAW+JPEG, then the JPEGs will be generated from RAW using the color profile you have set in your camera.
So as my esteemed fellow member has already suggested, I would second his opinion. Import your RAW file in editor, edit in aRGB color space, after all editing steps are completed convert the color profile to sRGB, save the photo as JPEG.

I'm still trying to get a handle on all of this. In NX2 in the color profile options I see Adobe RGB (1998), Nikon Apple RGB, Nikon Adobe RGB, Nikon sRGB, sRGB IEC61966-2.1, Spyder Calibrated (I do have a screen calibration gizmo) to mention just some of them, and I'm not sure which one you are all talking about. And then, if I have an ICC for a printer, when do I use that? When do you use an "output" ICC as opposed to an "editing" ICC?

When doing the editing, I keep everything (NEF, TIFF and JPEG for printing) in Nikon Adobe RGB. If printing myself I then apply the printer's profile.
When producing the final product for the web, that jpeg file is resized, compressed and saved in Nikon sRGB color space. The colors are subtly rendered differently and quite a few bits of color info are dropped, however the overall effect is for more brilliance and better contrast on the average PC screen monitors of viewers, including ours.
