2 Logo Questions

I'm setting up the Magazine theme for my disco website, but have a couple questions about the logo.

It has a transparent background, but when it appears on the theme, it gives it a grey background.

Is there a way to get it to appear further up the top of the page, level with the search bar?

I've included the image I'm using for the logo with this post.

If anybody in the South of England want a disco or karaoke, then get in touch ;o)
