Advice for Grad School (EE/CS major at UCLA)?

<p>I've got a 3.63 GPA, along with 610V/800Q for my GRE scores. However, I've really lacked any research/interaction with professors in my undergrad work besides taking classes. I've had one internship so far and I was planning to get one letter of rec from my boss there (is that a good idea?). Are there any suggestions on what I should do for the other 2 letters? Also, I'm looking to see if anyone would know if my stats would be on track for applying to UC Berkeley, UCLA, UCSD, and similar schools for a masters degree in EE/CS. Thanks for any help!</p>
