Points default questions

Hi, I'm a LDD/X-Civil 3D user configuring Carlson 2011 & have hit a couple of stumbling blocks relative to point defaults.
1. Where can I set the default attribute text height?
2. What is the best way to seperate symbols from points. They are all contained within a block sort of the way C3D had them in a style & we like to strip points & leave symbols when sending files out to a client.
3. I'm having issues with the X marker block. I set the scaling for my symbol & it seems to want to control that point symbol too. Don't really know why it's there. can I iliminate it & just use PDMODE to get my X from the AutoCAD point?
Thanks for any help. New to Carlson so I may be thinking to Civil 3D like.
P.S. cool thread on the evening gowns.
