Hi guys. I know this may come across as blatant spam, but I don't intend it to be that way. I have created a Dreamweaver extension which provides code completeion, syntax coloring and code hinting for all wordpress functions, conditional tags and template tags. It also has usage and function descriptions too.
I originally created it to make my own life easier and figured i would share it with the rest of you. You can get it from my own WordPress blog here
I hope it helps with your wordpress developing.
