Hey dogtown, I don't think your chances are bad at all. I would definitely apply to a large range of schools to keep your options open.
My stats were not as high as yours last year, becuse I worked a lot. I spent a lot of time worried about my application and finding fault with grades, mcat, etc.., when really, what's done is done. Once I realized that, I focused on the interview and tried to prepare for is as best I could. My doctor also volunteered his time to go over my application with me and give me some interview advice (he was on the admissions committee but was not part of the group that voted for me). I did get in and I believe a lot of it had to do with my work experience and my interview. A good interview can really make your case, so don't let anyone here tell you otherwise.
Admissions committees are only human and they understand that not everybody can do a lot of extracurricular stuff because they HAVE to work. At this point, just try and keep your grades up this year and start really working on your interview. Keep up with current events and start reading USAToday, today, not tomorrow or next week. Smile when you talk and look at people in the eye. Speak with confidence and don't let your voice crack, and above all, if asked about low grades or whatever seems "bad" on your application, don't make excuses. Just take responsibility for it and explain what happened. If you are nervous and say something silly, just tell them you're a little nervous. They probably are too. Interviewing people is more difficult than it looks.
It worked for me....
