David,
Once you have a good star image you can read it into MaximDL, just select on the PSF Model tab page "From Image" or alternatively if you save it in a fits file select "From File". I think internally MaximDL saves PSF images as FITS normalized to 1.0, but the original star image should not be saturated or you lose imformation. Hope this helps.
Its not an exact science, as sometimes I get a decent image, not especially different from previous ones, which simply will not yield to ME decon. Then I use LR decon - you know your done with LR when the Image Chi Square is minimized or bottoms out.
