You should follow what @bebraw said. Also, I would like to highlight the point where he suggests turning on gzip on the server. This is a great step towards optimization and will further compress your minified code. Once gzip is on, you can use a tool like pingdom to see the gzipped size and compare both. For example, a minified JS resource with size 1.5mb, when served with gzip on, could take up only 600kb (just an example, results may vary).
