I'm absolute rubbish at doing HTML these days, which is ridiculous considering how skillful I was when I was in junior high, apparently it is NOT like riding a bike.
That aside I was looking at some comics linked on pages for the templates I was thinking of giving a try and I saw that they had other random pages like 'about' and 'cast' and whatnot. I was wondering does DD support those pages or do you have to find somewhere else to host them.
also is there anywhere that does premade navibuttons and the like other than the ones provided in the templates?
Yup, DrunkDuck has the feature where you can upload "extra" pages.
As for uploading extra HTML pages? Well, in your Comic Panel, click on Files. This will take you to the section of the site wherein you can upload images, HTML, and even text files. To do this, click on:
As for a site with premade navigation buttons? No idea. D:
