Businesss Blog 2.1.3

having a lot of difficulty getting this blog to work correct.

1) It doesn't allow me to use my custom logo unless I select "No" under "Do you to use a custom large image logo rather than domain name text?" in the Branding section. Exactly the opposite of how it is suppolsed to work.
2) Also, not clear how I can get the navigation working? I want to display the pages. While I can do this by creating a custom menu, I want it to do this automatically as I build out new pages.
3) How do I remove the RSS feed option? I don't want to post this on the site.

Is there a user manual for this theme?
