On one hand I hope this is moot because I hope you solved your problem, on the other hand I don't want to waste my time. But this is fun so far so the latter wont be an issue.
Their Reports: Research Paper template IS in proper MLA format as defined by Purdue University's somewhat definitive style site:
and according to my SparkChart. They did choose an nonacademic font but that's up to your teacher/dept./school because MLA does not specify font but if that doesn't look MLA-ey enough then try converting this to pages then making it into a template.
Bottom-line: I'd try the existing pages template, run it past your instructor and make any changes (which will be minor) and save it as a new template.
P.S. I've been through this all before, my friend...
