Without seeing a screen shot it's hard to help.
All that really matters is the green in the immediate vicinity of the subject, the rest can be handled with a garbage matte. How much work you need to do keyframing that matte depends on how much the subject moves around.

You can try adding a little Gaussian blur, that may even things out. Do you have a still photo of your shoot you can post?

Last time I had a similar problem with an 3 years old green-screen clip I tried everything available for a full day - like Sony Sharpening or Sony Convolution Kernel.

What really helped at last was applying the NewBlue Detail Enhancer before the Chromakey FX.

post unprocessed video sample (a video file in a sharing site - not youtube, etc.) for us to test (preferably a scene with motion or "hard-to-key" scene)

I haven't done enough complex compositing in Vegas to guide you on this process - I'm sure someone here knows how to do this in Vegas - but in After Effects I have copied the green screen clip to another track, used levels to even out the screen exposure and applied the keyer to the Leveled track, then used a track matte to apply the alpha channel to the original clip.

One of my first green screen efforts ended up being impossible to key out. Now I always light chromakey with five lights: two soft lights lighting the heck out of the green background, one narrow LED strip behind the talent backlighting him or her to avoid spill, and two on the front of the talent so that there are no shadows (hardly artistic, but at least it keys).

On this early job (which was a series of interviews with a bunch of young skateboarders) what I ended up doing was setting up two layers with the same interview shots. I turned down the saturation on the bottom layer and keyed the top layer as best I could. This gave the effect of a plain canvas interview background which at least wasn't green. Slop in the key was just a bit of black and white at the edges and far less noticeable than an otherwise lousy key. For what it's worth, here is how it ended up. Not what I had planned, but respectable:

Looking at it again, I remember that I also did a bit of Photoshop matting of the background so that I could get better framing. I also applied a bit of artificial vignetting to the bottom layer which really did improve things.
