Anybody have a lot of experience with ListContourPlot and 
ListDensityPlot?

I have a matrix of data I want to plot and show for a presentation.

The problems I am having are as follows

with ColorFunctionScaling->True, It doesn't seem that the colors have 
any thing to do with the actual values if I use a legend and use 
ColorFunction->Hue, the scale is on the plot doesn't equal the legend 
since the data is truncated to fit 0-1.

I'm trying to divide by the largest value since all my data is positive 
and then the legend color scheme should fit the data plot except I don't 
have a zero in my data to peg the lower end.  I hate to add a zero in my 
matrix just to fix the lower end of the color scheme, is that the only 
option?

I can delineate which contours I want, but I can't label them.  Is there 
anyway to print the value of contours?  That is on the plot have each 
contour marked so that it isn't just a bunch of lines? 

Thanks in advance,
Paul
