So I guess my question is this: Is there a way to access the kind of layout functions you get when first making a directory, after you've made one? Or is that layout just set in stone?

In order to access those _very_ settings you'll have to create a new link directory template.
However, the templates are fully customizable using regular HTML tags and syntax. So to edit the template code directly you need to go to Preferences -> Link Directory settings -> Link Directory templates -> (select your template) Edit.
