High GPA, average GREs? Should I be worried about Lehigh grad school admission?

I'm a psychology major at a highly ranked private liberal arts college. I have a 3.7 GPA, and a Psych GPA of 3.73. My internship boss is writing me an excellent letter of recommendation for grad school, and I'm sure one of my psychology professors will as well. However, after taking some practice GREs, it looks like I'm only scoring around 600 Q, 500 V. (I'm taking the real ones next month). I want to be accepted into Lehigh U's Master's program...do you think my high GPA and good letters of recommendation will outweigh my not so great GREs? Thanks
