You will find answers to some of your questions here:

The algorithms implemented in Parallel Spectral Deconvolution are fairly simple.
I have also implemented another plugin - Parallel Iterative
Deconvolution, available at

http://piotr.wendykier.googlepages.com/iterativedeconvolution

This plugin has four iterative algorithms to choose from and two of
them are nonnegatively
constrained. The description of the algorithms (links to the articles)
is on the plugin's website.

There are no limitations and Parallel Iterative Deconvolution supports
spatially variant PSFs.

There is no user's guide, since there is no single recipe to do the
deconvolution.
You just need to try all the methods that I provide with different parameters
and hopefully one of them will work for you.
