The mounting question I answered already (but not yet if you are reading
your mail from oldest to newest). I'm using the mount on the tripod, not
the camera.  I'm pretty sure that gigantic lens would tear my little
plastic camera body in half. 

The center column is a no.  I'd hate to tip my tripod over with my
expensive lens on it.  I use it all the time on a wide lens to bring the
camera up higher, but not for a heavy telephoto.  I've heard that for
really sharp images I should not even extend any of the tripod legs, but
for the shot I was making I needed all the sections extended to get up
over the crotch of the tree.

I'm pretty sure its not a focus issue since I locked everything down and
then just cycled through the apertures in Av mode to compare the shots.

The 300D is the Digital Rebel, so there is no film.  :)

The things I've read on the internet, and the emails I've gotten from
this question lead me to believe that my first action should be to
replace the head.
