Answer 1

You don't need to run QAD from within a remote session, you can try it from your admin station:

Add-PSSnapin Quest.ActiveRoles.ADManagement
$pw = read-host "Enter password" -AsSecureString
Connect-QADService -Service 'server.company.com' -ConnectionAccount 'company\administrator' -ConnectionPassword $pw
Get-QADComputer QUAG | Select-Object -ExpandProperty CanonicalName

Answer 2

I think the problem is with the way you're declaring and then invoking that script block. Not tested, but I think this might work better:

 Invoke-Command -Session $session -ScriptBlock {
 Add-PSSnapin Quest.ActiveRoles.ADManagement
       }
 $ou = {get-qadcomputer QUAG | select -ExpandProperty canonicalname}

 $adou= (Invoke-Command -Session $session  -ScriptBlock $ou)
