Do you manage the Wordpress blog installation yourself?
As part 2 will detail, the whole purpose of switching to Wordpress was to reduce the work load of building/maintaining the site. I fully agree, Wordpress is swimming in tutorials, docs, and sometimes guides disguised as advertisements for a paid theme.
Re. changing fonts - My actual first thought was 'Surely I just need to find the settings in WP that let's me change the theme's font', and my experience was that Wordpress did not 'natively' support this.
