In terms of temps, warming up a little when stopped is pretty typical. OK as long as it does not get too hot.

Warming up while driving would be more concerning to me. With good airflow at speed I would expect the temps to hold just over T stat temp with a healthy system. Speeding up the water pump may help but I wonder if there is another problem. Radiator not sufficient or maybe water pump not sufficient? Did Glendale sell you the radiator?
