I can answer question 1. To read downloaded fanfiction, or any other pdf/epub, you need a reader app. I personaly use the free version of ReadEra because it's the best I've found in terms of range of file formats, general functionality, and ease of use. I like it enough that I plan to spring the $10 for the paid version eventually. Source: about 1 year ago

There are a number of ways to go about building the frontend. You can use the built-in Gutenberg editor, or the classic editor, choose a theme from https://wordpress.org/themes/ , or write your own theme from scratch, or purchase page builders like Elementor, Breakdance, etc. (I personally do not recommend them).
