Changes to the single blogger layout and Write Layout

Could you give me the code to hide the section of the single blogger layout where it says "Blogger has not set up their biography yet"? See attachment C:\fakepath\Screen Shot 2013-11-29 at 5.30.44 PM.png

Also, I would like the code to hide the tags and publishing options from the write layout shown in attachment C:\fakepath\Screen Shot 2013-11-29 at 5.36.41 PM.png

Could someone please help me out with this?

Thanks!
