Googling on free dictionaries gives you a lot of freely available dictionaries. If you upload them to a database, you can do a fast lookup for a known word.

You should have a look at password cracking applications! The simplest extension of the dictionary attack is to combine words. Moreover, there are other types of attacks, like replacing characters, that are close to each other on a keyboard. (For example: turn d to f.)

The best password cracking application I've seen so far is John the Ripper. If you see, what kind of attacks it uses, you can build a better password generator.

You should also study user habits, because a typical password is a bad password. For example, most users put numbers in their passphrase's end, so a strong password is, which has a number in it's middle.
