Custom Wordpress Fixes - 2

For my site [login to view URL] - Every post on the site is preceded with a ">>" in the title for some reason. I'd like this part removed. - When adding media to posts, everything is all out of alignment. This is likely related to a WP upgrade. I need everything aligned properly so it's not a hassle to add images. - If you go to the bottom of any post, there are 'Related Posts' - in between each post there are '...' I would like these dots removed. I would also like for the 'Related Posts' widget to be above the 'Leave a Comment' widget - If you go to [login to view URL] and Upload / Submit a wallpaper nothing happens. I need this fixed so I can submit wallpapers and they show up on site. This used to work, probably related to server transfer.
