Here's the bad news:
You're not going to get in anywhere that you want to go this year, especially not for theory, with these scores. Now, that is the bad news.
Here's the good news:
You seem like a very strong student, and your score certainly does not reflect your ability considering that you haven't taken courses that amount to about 50% of the material covered. I don't doubt that, after taking these classes, you can do well on the pGRE if you study. So, your plan of attack should be this: finish strong this year, prepare for the physics GRE like your life depended on it this summer, and reapply next year.
So basically... focus and do well this year, study your ass off over the summer (it works, I boosted my score by 200 points), and then reach out to potential advisors once you get your score and indicate your interest in the work. You can also make yourself more attractive by applying for things like the NSF or other fellowships. Above all, don't give up; your pGRE score is by no means a fair indicator of your knowledge given that you hadn't seen ~50% of the content!
