I just posted a few Powershell commands that might be useful to you. Check Application Pool name IIS 7.5 On SharePoint Server 2010

I would say, don't modify anything directly on IIS. Either use the SharePoint Powershell SnapIn cmdlets, or use the CA.

All changes directly in IIS is unsupported.
You usually create a new (web) application pool if you have a new security boundary. For example one account for internet and another one for extranet.
App pools tend to hog memory as well, so if they use the same account it makes sense to create one shared application pool in SharePoint CA or PowerShell. After you create it set it for the web applications in question either in CA or again PowerShell
