I 
be concerned
with  using a thrust bearing?  I wont be looking to add anything more later  
since I have a small
city lot and want to be nice to my neighbors.  

IMO thrust bearings are way overrated. For this  moderate load, you really 
don't need anything. The rotator will take the  vertical load and the tower can 
take the horizontal load so no problem. Save  your money.
 
    OTOH with large, aggressive loads they can be  useful.
