Replacing a motor is not too hard but you should be familiar with electrical wire and proper handling of electricity before attempting something like this. The only things you need are the new motor and a seal kit.
As for preventing this in the future, you need too give us some details on your setup and location. Location can be important if you winterize and are not pulling the pump each winter. Your setup can be important if there is a reason the pump is operating too far outside the best efficiency point. So questions:
Location
Do you winterize and if so, what do you do with the pump
Pump Model#
Height of pump relative to the pool water level
Diameter and number of individual suction pipes from the equipment to the pool
Diameter and number of individual return pipes from the equipment to the pool
Diameter and number of return eyeballs
Distance from the pool to the equipment
Filter type and backwash valve model if known
Filter PSI with a clean filter.
Heater - yes or no
Pool/Spa Valve - yes or no (If there is a spa, the number of jets and size)
Check Valves - Number and locations
