So, if Viz is selling homestuck books, and potentially advertising on the new website, are they gonna run into any copyright issues? Surely the stills from Con Air, the iron lass suit, thresh prince, johnny 5, or even the images used to construct derse, prospit, the planets, etc, must be a problem? Or do I not understand copyright?

There were already Act 1-2 Books and also ads on the website before, so like, there’s not that much of a difference other than the fact there’s a bigger company involved with Homestuck now. Stuff like that likely could fall into Parody territory, but even if it didn’t- Chances are if any of the Companies or Movies Homestuck references had Copyright stuff they didn’t want to see in the comic, they would’ve already acted against it, specially given Homestuck was way more popular at its peak than it is right now. If anything, Hussie being a single person would’ve had less luck dealing with copyright issues than VIZ as a larger corporation if they wanted to sue him. I don’t know how Copyright works 100%, but in my eyes, I’d say it may be even safer with VIZ. Unless VIZ preemptively wanted to do something ‘just in case’, it’s safer than it was before, and thus far they haven’t change a single thing about the comic, so they don’t quite seem concerned.
