You have not told us where this address data is from, how accurate it is or 
how it  is licensed.

Is your plan to come up with an automated method of detecting if the address 
point touches an existing building, or was your plan to manually inspect 
each address point and attach it to the building.

Automated matching imports are hard and generally discouraged by the 
community.  Either way you would need to make sure that you don't add 
addresses to buildings that already have address information.

One option might be to turn your address points into a background tile 
layer.  Then when mappers trace the building outlines they can just add in 
the address for the building they are tracing at the same time.
