Header customization and button image

Hello all!
Wondering if there is a way that I can customize the header area of geocraft, I am not a coder. I would also like to change the image button. Can you take one look for me at www.gimegamarketing.com? I am uploading a screenshot of what it looks like now. I am having a custom logo made. I adjusted the size of the logo on the site now, it is a bit big, I would like to make it a bit smaller but not very much. Any help you can give me is appreciated.
Thank you,
Julie
