I think the fact that you have a lot of post-bac and grad courses will reflect well - nothing will erase an undergrad GPA, but what you did definitely was good. I think uphill trend is positive, and shows you can tackle grad courses.
I think with these numbers, you have a decent chance, provided you picked schools wisely and have great ECs/letters.
Any other things that you may have that you might want to mention contributed to your low GPA should be mentioned, either by a letter writer/adviser OR by you in the optional section. Things such as working full time jobs to support family, intensive hospitalization, etc. If there is no legitimate reason, don't look for one and write something down.
Also, if you are disadvantaged, URM, or first college grad in your family, that will help as well.
Good luck!
