You can check out the resource section, I have posted up some notes on the symbols of Buddhism and there may be other notes generously donated by other people on the myths and customs on Buddhism. There is only one problem though, you cannot get access to the resources (you need to login but there is some technical error i guess because I can't seem to log in)
For the meantime, check out these websites:
BuddhaNet - this is a website which was recommended to me last year by my teacher
From Wikipedia but I don't think you should get much major information from here, the first website is more rleiable and should provide you with enough information
