Need Help Making A Theme

First of all I’d like to say I feel like a complete ass asking for so much, but I am completely lost. I’m currently trying to edit a theme (Relaxation) which can be seen on my website (www.fungkoo.com). I’m trying to edit it just because its roughly close to what I’m trying to make. I’m basically trying to copy the look of http://www.mfisn.com. If possible I want the whole thing to be roughly the same width as the Relaxation template already is and have it so its the same Two Column layout except with a logo on the top. Can anyone help me out or tell me where I need to go to learn?
Thanks tons.
