One small tip: it is usually very convenient to set the origin up at the center of the part. This way you can use the origin and the principal planes for various things. In this case as a mirrior plane. This good modelling practice has 1001 benefits besides mirroring but it may become a hindrance every now and then (design intent).
Additionally, holes and round protrusions are almost universally used for mating to adjoining parts. If multiple Datum Planes go through the center of a circular feature (male or female) then more types of Assembly Mates are offered during Assembly.
So before you ever start the Part, you almost need to ask yourself, "How will I join this Part to the next one in Assembly mode ?"
Hope this makes sense.
