Catch Shop Header and Logo

I have used what is called Catch Shop as a free word press theme, and must say it looks great! My question is: Is it possible in the header to move the logo to the left so its not right beside the header title? Also, the tagline that's directly below the Title can it be centred under the title? Last thing, can the empty space below the title and tag line be reduced? Would like the space reduced between the tagline and the page title. Any help would be appreciated. Thanks
