So, you would copy the / advanced / editor _ui.css themes to your own location, edit the colors and should be fine.
.mceEditorArea { font-family: "MS Sans Serif"; background: #FFFFFF; }
font size
tinyMCE.init({ ... font_size_style_values : "xx-small,x-small,small,medium,large,x-large,xx-large" });
Anyway, google is your friend
