Preferences Tab -> Name Format
There you can specify the formatting of player names, selecting from one of a number of predefined formats. It's actually fairly easy to add new formats to this, so if you've got a preference that isn't listed, request it. I don't want the list to become overwhelming, but so far I haven't had any requests for additional formats.
I'll add your "....s -> alternating colors" request to the to-do list. Seems reasonable.
If you're looking for help on HTML, just google "HTML tutorial" or "HTML reference". You'll get an amazingly large number of hits (not always good, but in this case there are tons of tutorials and help/reference guides out there).
