Haven't heard the Parasound specifically but I can confirm that the Q350 are way less demanding than the LS50 - power wise that amp will drive them fine as would almost any decent 50 Watt amp Marantz PM6006 Rega Brio etc
As to the amp/pre/speaker match I'd buy if possible with return policy just in case for whatever reason you have a mismatch on your hands.
Nice speaker I actually like them better than the LS50(more bass, more fun to listen to at the expense of a bit of detail) I'm sure you'll enjoy them once you get everything set up...
