Good advice to back the bow down to 65# or maybe even more. You could try broadheads and see how they fly. If they're irratic then you'll know for sure. My experience tells me the 5575 is way underspined and even 7595 (340 spine) might be marginal. I would advise you to lean more toward a 300 spine. I decent budget arrow for this would be a Gold Tip Expedition if funds are tight. Try a half dozen. If they work you can always get another half dozen later.
As for the sight setting being to the left? Almost any bow with a cable guard will require the sight pin to be to the left of the string. This is due to several things, but mostly because the cables are pulled to the side causing limb/riser torque. This torque becomes even greater as the bow is drawn and more force is shifted from the string to the cables. Then there's always the possibility that you have some astigmatism in your aiming eye (I have bad astigmatism). Arrow spine could be another contributing factor. In other words, tune the bow where it needs to be and then shoot it.
To give an example about the astigmatism, I have two friends that shoot my bows once in a while and with my bow sighted for me they both shoot approximately 8" to the right at 20 yards. I'd hate to think what the results would be at something like 50 yards. The point being---different eyes see different things. I just accept it and shoot the bow.
