Calibration of Dell 3007wfp-hc and color space use for web images

I have a Dell 3007wfp-hc on a Dell XPS410 running XP with a Nvidia GeForce

7900GS card. I have calibrated the monitor using an Eye-One Display 2. The

results after calibration are gamma 2.2, temperature 6500 and luminance 120. I

am using the latest versions of Photoshop and Bridge CS3. My default color

space in Photoshop CS3 is Adobe RGB.

After launching a photo via Bridge into Photoshop through Camera raw my color is

good.

If I soft proof to Monitor RGB from Adobe RGB it looks the same. My

understanding is this should be the case. Is this correct?

If I soft proof to Windows RGB from Adobe RGB I see a color shift to a less

saturated environment. My understanding is this should be the case. Is this

correct?

I then convert profile from Adobe RGB to sRGB IEC61966-2.1.

If I soft proof to Windows RGB from sRGB IEC61966-2.1 it looks the same. My

understanding is this should be the case. Is this correct?

If I soft proof to Monitor RGB from sRGB IEC61966-2.1 I see a color shift to

what I would describe as more saturated, but that is probably oversimplifying

it. Is this what I should expect?

My goal is to get the jpegs created for my website, so I can see that running

from the sRGB color space through Save for Web & Devices will get images that

look good on most non-calibrated Windows monitors. My concern is that those

same photos (which I actually reviewed on other computers that look good) are

not as pleasing on my calibrated monitor in non-color managed applications (i.e.

any web browser on Windows).

Is my monitor not accurately calibrated? Is my goal to have the images look

good on my calibrated monitor versus most people?s non-calibrated monitor

unachievable?

Thanks for reading this long post and for responding, if you choose to do so.
