Fixing Theme

Hi there, Id like to fix/adjust a couple of things here, first one is to make the header smaller then my pic smaller too and I want to remove the blog post box where my email, if I do then it shows like a NO POST YET kinda thing there.

Id love it to be able to click on Facebook, Instagram and Playlist and open this on a new tab keeping always this one.

Finally Im trying to add a contact box at the bottom but is not showing the boxes that I load in the widgets/sidebar menu.

Thanks in advance!
