Unless it calls for 1" pipe, you should probably leave it at 1/2" - if you take it up to 1", then your headloss is going to be even greater as there's much more water that the pump has to push up against, so you will get less flow.
+1. i wouldn't change the diam. of your pump output. bigger pipes are only really beneficial for drains.
It's not like if you go bigger, the pump will pump less. It's just that the amount will flatten out so after a few sizes it's not worthwhile going bigger.
