Hey Chad,
To run Community Events, all you really “Need” is The Events Calendar and then of course the Community Events add-on itself.
Once those are activated, if you do not need anything else on the site then you can just delete all pages and posts, and then go about removing links to other parts of your site that you won’t use and such.
Now, the main caveat is that you cannot really make the main /events/ page URL the “home” page of your site by default, since this is not a real “page” that existing in your admin.
However, you might be able to just set up a redirect or something to do this – a plugin like this might work really for that: https://wordpress.org/plugins/redirection/
Then, certainly, you can just use the events page and the community events submission page, and don’t need anything else on your site. If you have more general WordPress questions, like about setting up Menus and removing pages or removing sidebars or something, just to keep your site minimal and remove all non-event content, your best bet is to use the ol’ Google and/or browse http://codex.wordpress.org for specific information on that stuff.
All this information should help – let us know if it does, or if you have any other questions.
Cheers!
George
