Proper after_setup_theme and wp_head cleanup

What you should do:

  • Read Where to put my code: plugin or functions.php? and apply the lessons to your theme.

    Themes are for presentation only. Remove everything not related to presentation: do not touch link and meta elements in the header. That’s plugin territory.

  • Remove redundant code. add_theme_support('menus'); is not necessary, if you call register_nav_menus(). update_option() should not be called on every page load. Check the existing options first, and change it only if you have to.

  • add_theme_support('post-thumbnails'); is questionable, if you remove the thumbnail size. Why don’t you just change it to 80x60? Then the thumbnails will still be available after a theme switch. This could be done with the other sizes too.

should I just copy everything from this function and paste it to theme_setup?

No, keep separate tasks in separate functions or classes. Do not mix different tasks just to save some lines of code. It is easier to disable specific features with a plugin, when you follow the rule Separation of concerns. rm_add_theme_support() does too much already, because menus are not related to image sizes.
