Asp.net MVC3 Appropriate Model Passing

I'm quite new to MVC and while I've been trying to follow the best practices , I believe I may not be understanding certain fundamentals of either

-a. Using models and viewmodels appropriately

-b. Passing models into a controller for validation purposes.

The general purpose of my program is to select a stored procedure from a list of stored procedures, create a form where the user can fill out all the appropriate input variables, and then to execute that stored procedure. The tool is for non-technical people, so I'm eventually going to have to do a good deal of input validation.

As such I have four models: A Script Model, a Parameter Model, a Parameter Enum model and a Query Model, and two viewmodels: a paramviewmodel that generates the form to fill out, and a scriptviewmodel that creates a listbox filled with the possible script choices. I am using a prewritten database system to fill out my viewmodels in an init method in my controller (which I'm not sure is the proper way to do this?).

The viewmodels are as follows:

Imports System
Imports System.Collections.Generic
Public Class ScriptViewModel

[Code]....

I'm trying to work out the functionality. Also, I think this may be too much code in the view, even though most of it is display code.

Anyways, I have two main questions. One, does creating a model in my controller, calling an init method on it, and then passing it to the view make any sense in an mvc context (if not, how would I proceed?). Two, if I want to perform validation on the form I output in my htmlhelper, but I want to use my query model validation (and not my paramviewmodel), how can I do that? Most of the examples I've seen involve a controller that recieves an appropriate model variable, and the binding is performed outside the controller itself. They then just check modelstate. Is there any way I could do something similar here?

Edit: Is there any way I can make the syntax highlighting less crappy?
