I have updated Theme Maker (from now on, TM) to fully support N900 Theming. Not only can you convert the buttons, toolbars, all the widgets, but TM themes also convert the fonts, the icons and bacground images.
Wwhat is so different from before. Base theme template is larger than before. It's mostly legacy support stuff and you only really need to touch the right third of the template if you are lazy. In addition you will have two new templates: icons and backgrounds.
Lemme show these to you:
The icon template contains all the apps you have by default in the launcher and also for different mime types, devices and some control panel items. I'll be adding a few more later on. Ideas for good candidates are welcome. The reason these are not Nokia icons is that we need to have a CC basis for the icons so that you can work on top of them. Nokia Icons are of course strictly copyright Nokia, so I just used these beautiful Oxygen icons to set a good example for you.
Backgrounds contains on the top part a full 4 screens wide image (3200x480), so you can easily put an image that pans nicely on the device. Under it there are / will be some bgs for some additional apps.
So, even if you don't have N900 yet, I urge you to download theme maker and the example tempaltes and start hackign for a new theme, because you will surely be able to install it on your beautiful N900 very soon.
Theme Maker comes with two default templates, one for dark themes and another for light themes. This should set up the basis nicely for your new theme.

[Edit: Forgot to mention that theme maker requires bigger java heap on linux than by default. OSX app handles it nicely, just doubleclick to open, but on linux you need to start with -Xmx1024M parameter. I'll add a .sh script to next release to easen the pain of linux users. Windows version will follow soonish. You can edit the theme template anyway already and that's the most important thing. ]
