We are in the same situation as Dave, as we were transferring tapes to a new 
3584 robot and labeling them upon checkin to the TSM servers. I also had the 
same concerns about using the our old tapes with the E07 drives but monitoring 
the moved tapes and observing them is use without any issues relieved our 
worries.
Lastly on the scratch
tape reuse if you have your devclass set to use the higher format( i.e.
3592-4C E07)
that when the server grabs a scratch tape and starts to write to it that the 
tape will be using the higher data capacity format. During the purchase of our 
robot, the scratch cycle process utilizing a higher data format was confirmed 
by our vendor's TSM consultant.
