Hiding Share (tell_friend) Icon from Linkbar and Separating Entry Icon from Entry Text

Hi, I've never posted on here before but I am wondering how to Hide the "Share" (tell_friend) Icon from Linkbar, it's the big plus sized icon and it only appears on the top entry for some reason:



Also, how do we separate the icon used for the entry away from the entry itself? Also, how do you change the font information for the date on the top entry? I was able to change it for every other entry but for some reason it had no effect on the top entry. The sticky post. Here's a screen shot of the icon NOT separated from the post and the date:



Sorry if I this is posted wrong, just trying to learn new aspects of coding. Thank you! :)
