I do it the same way as you and it's a hell of a lot better than this. Everything is set up specifically for the client/project you're working on at the time – SSH keys, Git config, documents, mail accounts, passwords, you name it. All focused on the specific project and all isolated.
As far as the initial setup is concerned, this is fairly easily scriptable. Pretty much everything in System Preferences can be set using `defaults write`, there's loads of dotfile management tools, and most other things can be generated with templates using something like Cookiecutter. You can get a completely customised user account in a few seconds just by running a script and answering a few questions.
