1. You can find pre-made themes here: http://codex.wordpress.org/Using_Themes/Theme_List You can find basic instructions on making themes here: http://codex.wordpress.org/Blog_Design_and_Layout#Themes_and_Templates In all honesty, if you are new to HTML and CSS, and you don't know much about PHP, your ability to edit themes is going to be severely limited.
