Nicolas,

I presume that you get no answer because no-one has a MapServer available
for distribution that includes Oracle support.  It is not practical to
include this in the "stock" builds since it wouldn't work for anyone with
oracle installed (and the appropriate shared libraries in their path).

I would add that there aren't that many people using Oracle Spatial,
and apparently those who do aren't too chatty.  I have it installed, but
I haven't used it with the built-in Oracle Spatial support in MapServer
myself.

Generally yes, you should create seperate tables with bathymetry data
for different resolutions.  Or perhaps add a column indicating the
level at which each point should appear.

I have no idea.

I believe you need to apply a symbol.  Last I knew that was the only
way to make "fat" lines or points.

Good luck,
