A squirt of oil might make the motor last several more years. Can't hurt, at
least to try.
Agreed, get a new blade. Sometimes even if you can get the old bade off,
it's not going to fit the new motor. And it may be out of balance.
Being Mormon, I don't drink, and so don't get DYI trouble with the cops.
UV resistant nylon tie straps are good, for wires. Clip the end off the
wrap, so the end doesn't droop.

Agreed, you should try oiling it first..
Also even if the fan blade is fine, you may want to get anew one because it
may be difficult to remove the exiting blade from the motor.
Be sure to keep track to the direction of spin of the motor CW or CCW , the
direction of spin the blade is designed for, the pitch of the blade and the
HP rating of the motor.
Also pay attention to the location of the blade how far on the shaft it is.
I'm a DYI guy and successfully replaced the blade and motor on my heat pump.
Just pay attention to the details.
Another detail is the routing of the wires, they must be securely attached
so they don,t droop over time and get clipped by the blade.
