Okay, I know replying to myself is bad, but I discovered that by  
putting -Ix.x.x.x into the fstab in the options section makes it work  
as it does from the command line and placing the passwords in  
roots .nsmbrc allows it to mount from fstab without user input.

So I'm still at 1, I need a way to check from a script if the  
filesystem is mounted, I was thinking of setting them as 'late' in  
fstab and just calling mount -al prior to running the backup, but that  
would only work so long as the mounts were successful. So really I  
still need to check that the fs is mounted regardless.. I don't know  
of any way to check this other than calling mount with no  options,  
which doesn't really make for easy scripting.

Thanks for any ideas!
