Yes.

You aren't escaping the quotes. This is basic command line knowledge. 
Try replaceing the outer quotation marks with single quotes, and if that 
doesn't work, try "man sh" on the Nagios server...

Yes. Read up on escalations in the nagios documentation.

Yes. Read up on passing commands to nagios through "the command pipe". 
It's all very well documented.

Yes. Since it's obviously not important when this host goes down during 
the night, so long as it is up again in the morning, you can simply turn 
of checks (by creating a special timeperiod) for the host and everything 
on it from the time where downtime may first start to whenever you need 
it to be up again in the morning.
