Rossi46: AndrewBell has some good ideas, I myself use MCP, ReqAttack, and Magic Menu. Although in my experience, MCP was tricky to get working on my system, make sure you get the latest version.
VisualPrefs was mentioned, but I had much trouble with it under OS3.9. You might also want to try Birdie. Also, there are several programs to display a random WB/window pattern on boot.
As for MWB, seems like people either love it or hate it.... check Aminet for different palettes, backdrops, etc. and just make up your own mind....
