First, the native d3d9.dll caused TF2 to crash as soon as I clicked to launch it (though Steam seemed to work fine), and while the native d3d8.dll file doesn't seem to cause any problems, it doesn't seem to perform any better than the builtin file.

Yes, that's all you need, to remove wine (if you want to install another version) and remove its folder, be sure to backup anything though. Also, remember that all your wine configuration will be lost. The prefix means exactly what you figured -- the user folder. You can have multiple prefixes in wine, by running wine with the WINEPREFIXCREATE env var (someone correct me if wrong, please), and then using that prefix with WINEPREFIX.

Installing DX9 might get some DLLs which use unimplemented functions, or expect certain functions to behave in a way, while wine does not exhibit that behavior. It's always good to try and keep things to the wine implementation, which knows exactly what to expect from its code. Additionally, some Wine functions that the native DX use could possibly be implemented in a low-performance way, while Wine's implementation uses others -- just to throw in some random coins at the issue.

I think you should never even do what you did with those DLLs, since it definetely will not work. I'm even surprised that you managed to run the game at all in dx8, I suppose that either wine used its builtin DLL or something very strange happened there.
