This place (http://www.livejournal.com/tools/memories.bml?user=howto) and the LJ FAQ (http://www.livejournal.com/support/faq.bml) (scroll to customisation) provide tips on how to do things with certain styles to customise your journal.
Other effects besides glow can be found on this page. (http://www.lissaexplains.com/fun7.shtml)
