Dave,

No offence, but at some point you will likely need to master some
scripting language to give yourself flexability in doing GIS tasks
with a mixture of software.

There is no reason not to keep all the points in one file.  I don't
know anything about the "X,Y' extension so I don't can't address
that.

I am not sure how you are going to make proj ignore your siteid
column and only use the following columns.  Perhaps you will need
to use the cut and paste programs to split up and patch together 
columns.

OGR can write directly to CVS but does not place the geometry
in the CSV file (or at least not as separate columns).
