Thanks again for so much good info. My plan at the moment is as follows:
Reread Cohen, West and Aiken MRC for the behavioral sciences, familiarize myself with R and brush up on SAS.
I'll be doing all of this while also prepping for GRE (will obviously need to crush the quant section) and participating in research with a professor in hopes of presenting a poster in summer '15.
One last question, assuming I apply to several quant programs, would you recommend applying to some other areas of interest (ie clinical, social, dev) as backup?
