You couldn't get factory 19s on a 986, so Dan is wondering if the pressures he's using are correct since there won't be any labels. I do 32 frt, 37 rear with the 19s on my 987s, so you're close. You might bump your fronts to 30.

And all Porsche speedos run fast. They come that way from the factory. Your odometer is correct. Think of it as Porsche's gift to help you not get a ticket. However, if your new tires are taller or shorter than your factory originals, then you might change the speedo and odometer slightly. Taller will be slower speedo and fewer miles while shorter will be faster speedo and more miles.
