When attempting to open a work item attachment, we get prompted for credentials each time. Is this expected or something not set correctly Is there some permissions setting that will prevent this
All the users involved are in the project's contributors group in VSTF, in the contributors group of the sharepoint portal, and are browsers of the reporting services.

Opening WI Attachments Requires Username/Password

Have you verified your User Authentication settings in Internet Explorer (Tools -> Internet Options -> Security -> Local Intranet -> Custom Level -> User Authentication). Automatic logon should be enabled.
Have you tried adding your TFS url to your trusted sites list

Are users prompted for credentials when they connect to TFS
No.
Are users prompted for credentials when performing any other action in TFS
None that I've encountered.
Are users prompted for credentials when they try to download files from Sharepoint
No.
Have you made any changes to the default configuration of the TFS web configuration (\Microsoft Team Foundation 2005\Web Services\web.config)
No. And I checked the file to see if it matches your settings and it does.

A few questions to determine if this a client-side or server-side issue:
Are users prompted for credentials when they connect to TFS
Are users prompted for credentials when performing any other action in TFS
Are users prompted for credentials when they try to download files from Sharepoint
Have you made any changes to the default configuration of the TFS web configuration (\Microsoft Team Foundation 2005\Web Services\web.config) Specifically, these sections:
<defaultProxy>
<proxy usesystemdefault="false" bypassonlocal="true"/>
</defaultProxy>
<authentication mode="Windows" />
<authorization>
<allow users="*" />
</authorization>
<sessionState
mode="InProc"
cookieless="false"
/>
