Josh,
An axis 500 will probably shoot well for you. Don't know what your draw length is, but I doubt you will need that much weight up front unless you cut them shorter. I would suggest starting with a full lenth axis 500 and 125gr up front. Beman MFX Classic 500's will shoot the same and give you a heavier arrow, also a Carbon Express Heritage 150 would probably fly well. Bottom line you will have to experiment and see which works best at the length and weight up front you want. I think you're in the right ballpark on the spine with the 500's or 150's(C.E.).
