I Looooove stats! Go figure, since I'm not a techie nor a math whiz, either. I'm in a grad program, and after my fifth stats class I still love it. However, I'm glad I didn't pursue a quantitative psych grad program because, like you, I have other interests like psychopharmacology, neuropsychology and forensics. When I chose my academic path, the biggest deciding factor was - what do I want to do with this when it's over? Taking the stats path really meant research, and while I love it, I knew I didn't want that to be my primary job role. You can take the classes which will support you in doing your own thesis or dissertation project, or allow you to get the most out of reading others' research with a critical eye without focusing on stats so much that it dilutes your attention to other areas like biopsych. Good luck and happy SPSS'ing!
