Are there any other learning materials I can refer to for creating single page web applications using perl?

There are many resources out there. The trick here is that tools and best practices in this space evolve very quickly and the single page web application in this context is 70% JavaScript, HTML5, CSS, client side DB and payload packaging stuff and 30% RESTy backend Perl. There are some printed resources but they were out of date soon after being published. Examples include Building iPhone Apps with HTML, CSS, and JavaScript and Building Android Apps With HTML, CSS, and JavaScript. Mojolicious and Catalyst are also available as backends.

Online tutorials abound on this topic (though usually in its component pieces) and it's the best place to dig. I could not find (I barely tried but I did try :P) the tutorial/walk-through that came to mind of a couple of guys building a one-page interface to Facebook with HTML5 that was a lot better than Facebook's own app and HTML. The best resource I have found for riding the wave here is the Frontend Focus mailing list. I am so far behind on my own reading and skills that I'm no help here right now. Good luck! Please come back and share any success or specific questions you have.
