Basic Catch Box Pro Instructions?

I just bought Catch Box Pro last night. I'm happy with it thus far, but wanted to ask... 1) Is there documentation or tutorials or basic instructions about the theme (besides the web page advertising it... such as a "readme.txt.")? 2) Right now I'm attempting to control the font size. I found the options for the fonts size, but it would help if I had information about what areas of a web site each is applied. 3) I found the font-family options, but I have a font.tff that I want to use on my site... is there a way to upload custom fonts?
