WP Super Cache can be configured to use mod_rewrite which will bypass WP and PHP for serving pages. Super Cache should also be able to handle the generation of the static files so that you don't have to manually update them.
Another option is to use AWS CloudFront [aws.amazon.com...] Point your domain at CloudFront and AWS will serve them cached files from Amazon's network. If the file is not cached or the cached file has expired, a fresh file will be pulled from your origin server (this is the server you currently run on)
There are lots of ways to speed up your site using a variety of caching services. Hope this helps.
