Welcome. If you can hit a Driver 330 yards than I don't think you need to change what you have. My suggestion would be game improvement or super game improvement irons. I play Callaway Diable Edge Irons, which are in the SGI category. I would also go with some hybrid clubs for your 3,4,5.
IMO. Make sure the shaft profile of whatever driver you choose fits your swing.
With the wrong shaft too many of those 300 yard drives can end up 100 yards in the woods.
P.S. You can't go by how a shaft is labeled. Different shafts (even from the same company) labeled as "Stiff" or "Regular" won't be identical so buying off of the rack is a crap shoot, even if you have hit the same name driver with the same shaft label. A good club fitter can check the overall shaft profile to make sure it's what you need.
