Thanks for the question.

where to transfer my files after I've created my static page on my nav bar

e.g. your static page is
www.yoursite.com/resourcesYou set up an FTP connection in Preferences -> Link Directory settings -> FTP settings and set the folder where your site is (the main wordpress folder) as your root (remote dire setup -> -> select folder -> mark as web root).
Go to Preferences -> Link Directory settings -> Link directory templates -> Edit -> server-side settings and name your future directory RIGHT as your static resources page is named. In our case it's "resources". So just type in
resources
and select blank extension on the right.
This way when you click "generate" and upload the whole thing it will be available at the static address you have set in your nav bar.

why are fonts so big how to make em smaller

Most probably when you created a link directory template you selected the "area to be replaced" starting with your header and all your page has the style of the header. You can re-create your template or edit the code manually in Preferences -> Link Directory settings -> Link Directory template settings -> Edit.
You can click Help -> Send project to support if you get stuck, we'll take a look at your files and code.
