Grouping Topbar menus and removing notices bubble

I am customizing my admin bar for my network so that it contains global links and such. I have been able to make it sing and dance so far, but there are two things that I cannot for the life of me figure out.

1.) I would like to group “MySites”, The Individ Site Menu, and “+ New” under a single “Admin” menu. Is this possible without removing the current ones and rebuilding them from scratch under an Admin menu?

2.) More perplexing is that I have a bubble button at the right of the screen, just before the profile menu. It looks like an inverted comments bubble. I was able to remove the comments bubble, but I can’t even find what this “Notices” bubble is to remove it. Anyone have any ideas?

Thank you!
