<p>I want to use Powershell to write some utilities, leveraging our own .NET components to handle the actual work.  This is in place of writing a small console app to tie the calls together.  My question is where I would find a good source of documentation or tutorial material to help me fast track this?</p>

If you want to load an assembly into your PowerShell session, you can use reflection and load the assembly.
```
```
[void][System.Reflection.Assembly]::LoadFrom(PathToYourAssembly)
```
```
After you load your assembly, you can call static methods and create new instances of a class.
A good tutorial can be found

Both books mentioned by EBGreen are excellent.  The PowerShell Cookbook is very task oriented and PowerShell in Action is a great description of the language, its focus and useability.  PowerShell in Action is one of my favorite books. :)
