[Ducati] Changing fork oil in 916 w/Showa

I would appreciate comments on the following recital of my understanding 
of the procedure for changing the fork oil of my 1998 916 Showa forks. 
The forks are working ok but the oil is definitely over two years old. 
I'd like to use the easiest effective method.  It is my understanding 
that the following suffices.

1) Remove the fork tubes,
2) Holding each fork tube upright, back off the 32mm top cap screw
3) Invert the fork tube to drain the oil (measuring the amount of oil 
that exits the tubes).
4) while inverted, pump shock to remove as much oil as possible
5) optionally spray non-chlorinated brake cleaner into fork to clear as 
much debris/old oil as possible (again pumping shock)
6) Refill with _about_ 480cc of 5w oil per tube (should I measure the 
level of the oil first - what if the levels are different?)
7) take care not to rotate the stanchion relative to the outer tube (the 
seals at 35K miles are not leaking so I don't want to replace the seals 
quite yet)
8) I had planned on using Belray 5W fork oil.

I should have done this when I replaced the head bearings (with tapered 
rollers) a couple of weeks ago but working on a Ducati is almost as much 
fun as riding one so there is my excuse to have a good time.  Pardon me 
while I genuflect in the direction of Bologna. :-)
