Hello,
It seems like with you being new to networker and all cloning will require 
carefull planing with all the steps involved, backup and clone time, 
saveset vs volume cloning needs to be taken into account.
This may require scirpts, perhaps any one out there doing saveset cloning 
could lay down the plan for you and thier sample scirpts.
The easiest way around for you now might be use automatice group based 
cloning by just enbeling cloning in networker at group level, you may want 
to seperate your test enviroment with prod, as there may be several 
factors that can effect your cloning time etc, if the tapes need to leave 
in time each day, cloning as little as possible might be best approach.
Also look into having CDL do voume level closing keeping legato out of the 
mix, although tape utilization could become an issue, sizing VTL tapes may 
also become a factor.
Thanks
