I think the 500 series arrows are to light for the poundage your shooting,just my opinion.I would think the 340's or 400's would be better for hunting,as long as your bow shoots them,they would be stiffer in spine and heavier in overall weight for better penetration.I would prefer shooting a little heavier arrow at game,this is only my opinion.Can't give you an opinion on mechanical broadheads,I havn't had any experience with them.Good luck,you might want to check out the Easton shaft chart to get the right shaft size for your draw length and draw weight.
