accessing order infos in the pluginresponse view, how?

[Majere]

Hi,
I'm overriding the pluginresponse/default.php view because it is the page to which the user is redirected after paypal payment.
I'd like to show in it infos about what he purchased, such as items ids, items names, items custom fields.. is it possibile to retrieve this data and echo it with php? Thanks
Also I'd like to know if this page is showed even if the payment was interrupted or only if payment was succesfull, i couldn't find any documentation on it.

This could shown in shopper order details.
