meshc representation of scattered points

Hi,
I have a list of about 25000 points. Those points have x&y-values varying from 0 to 84 with a 0.5 interval. The z-values associated to those x&y-values vary radomly from -140 to -148 for instance. This list of points comes from a scan of a surface a made with a profilometer(a laser scan).

I would like to know a to draw a 'topographical map' of the scattered points and if possible to draw the mean plane of that surface on the same plot. I am not 'THAT' confortable with matlab so please be answer in detail.

Thank you

PS: I know how to to a multiple linear regression to obtain the equation of the mean plane but i do not know how to verify that it is the best fit.
