jQuery Grid Plugin - jqGrid

I implemented some "helper forms" for my grid using jqModal - now I'm trying to use the jqgrid popup dialog windows so I can easily maintain the same look and feel.   I studied the code and have made some forms but I'm having some problems with formating the dialog content and initialization...

My question is that if I set the jqModal to TRUE - does the "p" parameter use exactly the same option properties that are documented for jqModal plugin?      are their some that aren't?  

I see an option on the  viewModal()  function called "OnShow" - does this map to jqModal's  jqmShow() function?

I am studying the files grid_common.js and seeing how these functions are used by studying grid_setColumns.js files - are there other files or docs that I can read to find out, for instance, the entire set of createModal function options?

(sorry, i'm pretty new to javascript and unfamiliar with conventions, etc.)
