The Code tool is realy useful for putting the script in a readable format.
This isnt' a great location for generic, non SharePoint, PowerShell questions. A lot of us know it back to front but the hey Scripting guy forum is much faster than we are here.
That error message is actually very descriptive. It's saying there is no invoke method on a null object, or in other words there isn't an object to operate on. Or to finally put it in English: There is no '$shellApplication' object that PowerShell knows
of.
At the moment I've no idea what you intended to do with the $zipPackage object but since it's not being used now i'd just comment that line out
