UPDATE:

To verify that compression works, you could use Firefox with Firebug and YSlow plugins, they will show compression status for each component (html, javascript, css).

Also, in order to test each compression method (gzip/deflate) you could alter the "network.http.accept-encoding" preference in Firefox (default value is "gzip,deflate")

IIS Compression: Enable GZIP and DEFLATE using Powershell

Your initial line of attack with PowerShell is to use WMI. Unfortunately, the root\MicrosoftIisV2 namespace is set up with non-standard security settings which you can't change in PS (not in V1, at least, V2 may be different).

I would suggest looking at the IIS ADSI provider, specifically the IIsCompressionScheme object - http://msdn.microsoft.com/en-us/library/ms524574.aspx

You may be able to work with this in PowerShell by manipulating

$obj = [ADSI]"IIS://MachineName/W3SVC/Filters/Compression/Scheme"

However, ADSI is pretty evil, so you'll have a fairly steep learning curve.
