Mindy posted a link to lots of free fonts on her blog which are really nice.
I use The Font Thing to organise my fonts. It is by Sue Fisher (a fellow Aussie!) and it's brilliant because you can categorise your fonts (into "Collections"). For example, I have "favorite", "script", "handwriting", "kids" (for the funkier/kiddy ones), "picture" (for picture fonts), "typed" etc. If you find it hard to keep track of your fonts it's a must-have. The other great aspect is that you can type your text in the top and see exactly what it will look like for all your fonts.
Sue has lots of info on TFT on her website including screen shots. She also has links to other font resources including font archives and other software. Very handy.
There is a tutorial for TFT at DSP but they don't go into using the collections which I think is the best part.
Be aware though that if you have hundreds of fonts it can take a loooong time to generate the text in all the variations. This is another good reason to use collections because you are only looking at a subset of your fonts at any one time.
