Use hostgroups to create views. A host can be in more than one hostgroup
so you could have overlap if you need it. You'll be able to create
servicegroups in 2.0 I believe.

Nagios does this by default with authentication enabled. Users are only
able to see hosts and services that they are authorized contacts for.
It's well documented.

Remove the 'u' (unreachable) directive from your notification_options in
your host definitions.
http://nagios.sourceforge.net/docs/1_0/xodtemplate.html#host --
notifications_options: This directive is used to determine when
notifications for the host should be sent out. Valid options are a
combination of one or more of the following: d = send notifications on a
DOWN state, u = send notifications on an UNREACHABLE state, and r = send
notifications on recoveries (OK state). If you specify n (none) as an
option, no host notifications will be sent out. Example: If you specify
d,r in this field, notifications will only be sent out when the host
goes DOWN and when it recovers from a DOWN state.
