Currently required skills in most internships 
I just finished my first year in college and I'm currently looking for an internship opportunity. I just went through our college's archive of job postings from last 3 months and this is what I found out about what employers are currently looking for in the technical side:

    J2EE
    Scripting languages (perl/python)
    SQL - usually any flavor, mysql the most common
    Web Development stuff (html,css,xml,javascript,jsp)

Problem is I don't know anything from those except (x)html and CSS. I'm currently going through K&R C, not sure if I should stop.

My question is, should I be worried now and at least be proficient in one of those (I'm thinking web development) so I can at least be a bit marketable to potential employers?

I'm also looking for volunteer opportunities here and lots of them are looking for web designers, I guess you understand where I'm getting at now..
