Customize fonts and header

Hi,

I currently use Radcliffe, I like it, but there are a couple design elements I’m grappling with, Before I invest more time, I’d like to know if there are reasonable fixes or if they fall into the category of web development.

Here are the items I’d like to adjust (didn’t find them in forum):
-Customize fonts – change font style, and colors to a specific hex code in body text, titles, menu
-Header – make logo left justified (instead of centered) and in line with menu
-Reduce some padding in header area.

Thanks!
