Help formatting Powershell output

Hello Powershell Experts,
I have an output formatting question.  I have a list of about 40 Active Directory objects that are either users or groups.  I have pieced together some code that will evaluate whether the object is a user or a group.  It will then display which groups the object is part of or display a message that states the object is not part of any groups.  The codes not pretty, but it gets the information I need.  However, it is not formatted the way I would like it.
Here is the code:

$POLObjects= "Poldev"
foreach ($Object in $POLObjects){
    $Data = Get-QADObject $Object | select name, type
    $DataGroupMembership = Get-QADGroup -ContainsMember $Data.name | Select Name
   If ($DataGroupMembership -eq $Null) {$groups = "This user is currently not in any AD groups."}
   Else {$groups = $DataGroupMembership}


Write-Host "The Active Directory object $($Data.name) is a $($data.type)."
Write-Host "$($Data.name) belongs to the following groups:"
Write-host "$($groups.name)"

} 

Select allOpen in new window

Here is the output displayed to the screen:

The Active Directory object poldev is a user.
Poldev belongs to the following groups:
Document Owners Document Managers Records Managers Domain Users

Select allOpen in new window

Here is what I would like the displayed output to look like:

The Active Directory object poldev is a user.
Poldev belongs to the following groups:
Document Owners
Document Managers
Records Managers
Domain Users

My formatting questions are:
1.       How do I get the groups to be presented in a list?
2.      Can I have the list italicized?
3.      Could I get this sent to a text file as opposed to the screen?

Thanks in advanced for your help.
