Access Rights for Work Items

In my own process template I have a group of users calledDevelopers ([PROJECT]\Developers)with the only one permission ofPROJECT.GENERIC_READ = Allow, and I have a work item typeBug with the starting state Submitted without any limitationsFor orNot for some users/groups (i.e. any user can submit a bug). However, from inside the real project (process template instance) people from the group Developers cannot either submit new bugs or even view the exisiting ones (via queries). Thus, I have two questions:

1. What access rights must a person have (on the server/project/etc. level) to submit new bugs and to view the existing ones?
2. How can I update theGroupsandPermissions.xml in an existing project if I fix the problem with access rights in the project template? Or is there any other way to specify the needed rights in the existing project?

Thanks in advance.
