If you really want to get that GPA up, (and not for the purpose of going Greek, but because you are there for an education), you might try re-taking some of the classes in which you did most poorly. If, as you said, you had extenuating issues that contributed to your inability to do well in your classes, and those circumstances are now over, you should be able to do better next time around. Of course, it will cost you to retake classes and probably put off your graduation for a semester or two, but it could very well be worth it in the long run.

Whether it's the same professor - in which case, you can ask for guidance, or a new professor - which might make the difference in how the subject is taught, you might be able to really push your GPA up.

As for recruitment, you really have the cards stacked against you. I would estimate that the average time required during an NPC new member period would be equivalent to 3 credit hours or more, so what is going to be different this time around if you had that additional load on your schedule?
