How can I go about making the forum load into an iframe so I can maintain the main site's header and footer sections?

This isn't really EE specific - you'd load the forum in an iframe like you'd load anything else in an iframe.
That said - loading it in an iframe isn't a good idea. If you want to use your global header and footer (embeds/snippets?) in the forum then run your forum through the regular template engine using the {exp:forum} tag. More info about that here:

That way you can have a template group called "forum.group" for instance, with an index.html in it which has:
{embed="embeds/global_header"}
{exp:forum}
{sn_global_footer}
And voila, you have your global header / footer code around the forum. Then you'll need to dive into the forum global header and footer templates and remove some html there of course to make it work properly.
