Create a script to do the checks and change the 'Pre Shutdown check 
command' setting to call your script. Your script should return 0 if it 
is OK to shutdown or 1 if it is not. You probably should add a call to 
mythshutdown --check to your script  which already checks for things 
like mythfilldatabase running, comm flagging, in or about to start a 
daily wakeup period etc. I'll leave it as an exercise to work out how 
your script should check if MythWeb is active or samba shares are in use :-)

No you only need MythWelcome on any FE's. You may not need it at all it 
depend on how you want things to work. If when you exit the FE you 
automatically shut the computer down then you don't need it. If on the 
other hand you want the FE to stay up until the BE shuts down then you 
need it. The idea is you start the mythfrontend  from MythWelcome so 
when you're done for the day and you exit  mythfrontend, which will 
allow the BE to shutdown, you're taken back to  MythWelcome which if 
you  have it setup properly will shutdown the FE when the BE does. If 
it's a combined FE/BE then you really always need MythWelcome.
