I Love YTtalk
You could try #fr, #container { border:none !important;} within your CSS file, I cant guarantee that will work, it could though. I dont believe you can properly resize the avatars, you could try: #profile-picture { max-height:88px !important; max-width:88px !important; } in your CSS and see if that works.
Actually after a bit of research you can only style the Iframe when you have the CSS file on the same domain which would be youtube.com so I dont believe it is possible at all unfortunately.
