to edit your company title block, you should edit the file in your VectorWorks Application folder:
Libraries > Defaluts > Drawing Border - Title Blocks
then you can place a title block on your drawing, set it up the way you want, then copy it from one drawing to another.
I have cover this in detail in my Architect and Landscape tutorial, but you may not want to get it just for that.
