Which Open Work Permit goes with Inland spouse sponsorship app?

[Radium]

I know I've been asking too many questions and this question might sound stupid.
Can anyone please walk me through where I can get this specific Open Work Permit form that needs to be sent along with the inland app for spouse (my spouse has Post Grad Work Permit expiring June 2015, which I know is non extendible).

Do I've to take a print out and fill this OWP form? But if I've to fill it out completely and include with my Inland app will I've all the answers to it? The reason why I'm asking this is because there are some futuristic questions.
other option is filing OWP after first stage approval when we get our AIP letter.
Thanks again!!

There is no specific OWP application. The app is found here http://www.cic.gc.ca/english/information/applications/extend-worker.asp.
