How much stiffer is it with the sport shocks and springs? I'm considering doing the same to my 300. I'll likely leave the sway bars alone, unless that provides a massive improvement.
For our Passat, using the components I purposely selected for the suspension upgrade, the ride is still very nice. It's not "stiff" or "harsh", not even close. But this is no surprise and is exactly what I wanted for this car. I've always been a suspension tuner and have changed just about every car we've bought in the last 40 years. Literally. In other words, I know what I'm doing.
My primary advice to you is that you do not lower your 300S too much. This is a common mistake that people make on all cars. The biggest thing is that you'll be smacking the bump stops more frequently than you should be. This is not only hard on the chassis, it makes for unpredictable handling characteristics. Secondly, lower too much and you increase the risk of grinding your front clip on driveways and curb stops.
I poked around for springs for your 300S. H&R does not offer anything. Eibach does, the Pro-Kit. I've used both H&R and Eibach over the years and consider them of equal quality. Eibach makes a spring for your 300S but the Pro-Kit may lower your car more than you want (and the Pro-Kit is their most mild spring). Struts and shocks? If you do put lowering springs in your car, always install new struts and shocks. I've always preferred Bilsteins over Konis because of Bilstein's much stronger "monotube" design (in the case of struts). That said, I've found that Bilsteins for German cars are made in Germany, while Bilsteins made for American cars are made in USA. The American made Bilsteins are, sadly, of a completely different design than the German made versions. The only thing they have in common is the yellow paint!
I suggest you join a Chrysler 300 forum. There are many. You can learn a lot there. But once again, don't lower your car too much!!!!!
