Change filter in Stream

Hello,

I have a few question about the page "Community" :
1- I would like to remove "Me and my Friends" in Newsfeed on the left side (see attached picture, n°1) or at least that "Me and my friends" appeared in second after "Everyone". Is it possible ?
If not possible, where can I change the name "Me and my friends" ?

2- How can I remove the module "Applications" on the left side ? (Number 2 on attached picture)

Thanks a lot for your help,

Edouard
