1) yes, there are a number of regular summer tires that are available in a 255/30/19 Yokohama ADVAN Neova AD08, Goodyear Eagle F1 Asymmetric, Kumho Ecsta SPT to name a few. There is also no problem with upsizing. The car easily accommodates a 265 or 275. Some folks are even running 285 rears with the standard sport package adjustable m suspension.

2) yup, you can easily downsize to 18's if that's the route you want to go.

There are a few considerations about the 19's. Do yourself a favor and do a search on 19" wheels cracking. The style 296 wheels are cast wheels that in combination with the RFT are prone to cracking and bending. I know, because I bent 2 rims going over a pothole at 40 mph. I'm running regular tires now at 275/30/19. I'm hoping that the additional .24" sidewall height in combination with a softer sidewall will do a better job at protecting my rims.

Two - Alternatively, on a factory Sport suspension shipped with 19", is it possible to install 18" tires without modifying the suspension settings and not messing up later with alignment / camber, etc ?

Thanks for your help.

(I owned a Z4 2003 and I know the pain of the RFT - am looking at purchasing a E89 only if I can get rid of the 19" RFT. If possible I intend to re-use the very good Bridgestone 18' RE760 Sport from my VW GTI on the E89).
