Would I get the same results with a hdr image by taking a raw image and adjusting the exposure and saving it as a jpg. and doing this 2 or 3 times with different exposures then doing a photomerge?

You will get similar, but definitely not the same. The merged photo will be a lot nosier (grainy) this way. In addition to this, and perhaps more importantly, blown out parts will remain blown out and underexposed will remain underexposed.

Having said that, there is a niche for single photo HDR's. Photomatix has the option to load a single raw file and it does the adjusting exposures as you suggest internally. This is useful for subjects that are moving (animals, people, etc...)

I have done this with 2 different photos with descent results, what do you think? Here are before and after photos.

You've definitely improved the photos for sure, so nice work on that. The only problem that I see is that the top of the first photo's sky seems to be blown out. As mentioned before, a bracket set would eliminate this.
