The fire color appears to be in the medusa_s file for her. In the bottom half. Bond1 was using highres normal maps on these characters. Make a back up of both the _n and _s files and then play with the Hue to changes the color of the fire.
As far as the shadow goes:
/*******PLANAR SHADOW TWEAKABLES**************************/
//offset shadow 1/2 character's height in FPSC units to place at ground level
float ShadowOffset
<
string UIWidget = "slider";
float UIMin = -100.0;
float UIMax = 0.0;
float UIStep = 0.1;
string UIName = "bumpiness";
> = -57.000000;
Open the shader in notepad and change the last line in the code section I have shown above to -200 or just enough to hide the shadow under the floor plane.
Other then hacking up the shader code till you got it right this would be the easiest probably.
