Help with Editing my site!

[hellotati]

Hello! I literally just installed Zen Cart onto my site and am trying to personalize it! I was reading about how I can change it with the CSS (like html) right? but I am not sure where to find the forms to actually change it and how to do it!
I am using version Zen Cart 1.3.8a

Where do I go to edit things like font, colors, and even change the backround?

Please help!

P.s-are there other templates I can choose from? a
and where I can put my own big logo at the top?
Thanks for any help!!
