Yes, the [svn2git] and [svn] sections are normally set up by git-svn-mirror when starting from scratch. 
Yes, you should delete any [branch] sections from the mirror's config, and yes, once you do that you can't run git update (or git pull or fetch, for that matter) anymore. All input comes from git svn.

Is the receiving bare repo inited and the URL correct? Is this the first push to that repo?
