I forgot to mention to you that when you install Project Accounting, most of the affected resources in GP (Form & Reports) are going to get an alternative security entry...
To assign the users the PA resources, you should use Microsoft Dynamics GP menu >> Tools >> Setup >> System >> Alternate/Modified Forms and Reports
Create a new Alternate/Modified Forms and Reports ID and assign the resources to it. In return, you can then select this new ID in the user security to easily switch from the DEFAULT profile to the PA profile.
For your Revenue/Expense Deferral, you'll likely have to run the GP setup wizard to add the module into your launch file if this an optional feature of GP. Make sure your registration keys are valid for it.
The list of the registered modules can be reviewed here : Microsoft Dynamics GP menu >> Tools >> Setup >> System >> Registration
