How can I find what scom group a specific server belongs to using powershell?

Question

Environment:  SCOM 2007 r2
Server in question:  Running Windows 2003 Std. (yes I know this sounds crazy)
Why do I need this:  I noticed at the console level we have had server unexpected shutdown events which are not generating email notifications. 
Source shows: Windows 2003 Server Standard Edition
Alert Rule:  Windows Shutdown Unexpectedly
From what I see these are all windows 2003 server Std edition systems.  I did a track and trace using our exchange tracking system which confirmed the alerts were not being emailed. Not sure if there is a better approach for this, but not being a sql
expert (however I do have someone I can leverage) I am trying to see if I can somehow extract this information using powershell.
Secondary general question:  How can I find out the current size of our scom 2007 database and the number of objkects\servers being monitored? This is prep work for a migration over to 2012.
Thanks in advance for the help!

 $containmentRel = Get-RelationshipClass -name:’Microsoft.SystemCenter.InstanceGroupContainsEntities’
$computerClass = Get-MonitoringClass -name:”Microsoft.Windows.Computer”
$criteria = [string]::Format(“PrincipalName = ‘{0}’”,$computerFQDN)
 try {
 $computer = Get-MonitoringObject -monitoringClass:$computerClass -criteria:$criteria
 $relatedObjects = $computer.GetMonitoringRelationshipObjectsWhereTarget($containmentRel,[Microsoft.EnterpriseManagement.Configuration.DerivedClassTraversalDepth]::Recursive,[Microsoft.EnterpriseManagement.Common.TraversalDepth]::Recursive)
 catch {
 $_
 write-host “An error occurred while querying groups of $computerFQDN”
foreach($group in $relatedObjects)
 [array]$Groups = $groups + $group.SourceMonitoringObject.DisplayName
 if($groups) {
 return $groups
 } else {
 write-host “No groups available for $computerFQDN”
