Since you mentioned leet-speak...
Keep in mind that most of that leet-speak mixed character **** is already in the cracker libraries too right alongside the real words they sub for so you still need to mix it up.
Steve Gibson has a really interesting read on password entropy on this page. http://www.grc.com/haystack.htm
About halfway down is a podcast of the Security Now! episode where he covered it in detail.
A definite must-read and must-listen if you're security conscious. It might surprise you.
