I'd stress the importance of networking (the other kind): if you're somewhere with any sort of technology community, start attending local (free) events and meeting people in the industry. It's not a matter of going to the events looking for work, but to meet people. The more people you know, the easier it is to get what you want. Second, an online presence is a good way to get ahead of other candidates. An active GitHub account will go a long way with employers. A blog will too, if you talk about relevant topics. I'd focus less on specific skills and more on the ways you've demonstrated those skills. If you have worked on free-time projects, throw them up on GitHub and make sure the employer knows about them. Finally, talk to other students at your school who have had internships. Not only will they be able to advise you, if they think you're a good candidate they can put in a good word for you.
