Another idea to consider is splitting your summer between a volunteer job that provides great legal experience and a job that pays your bills. I spent my first summer workign at Any Mountain [a west coast outdoor store], and working as a student assitant at my law school. for 1L's, grades, and unfortunately connections are two of the most important things in getting a job at a great firm. Since you cant change who your daddy is, make sure that you NETWORK. Get involved with your local Charles Houston Bar Association. Also, try to take off a little bit of time at the end of the summer, ie a week or two, for vacation, so you'll be well rested for the intense first semester of second year. Most importantly focus on your grades during your first year, b/c that's how decisions are made for 2L summer jobs, which lead to permanent job offers. Good Luck!
