Leinad4Mind gave you pretty much the answers you were looking for.
It all depends how you progressively set the permissions for each groups. For example lets take the group forum permission for the following: User1 is part of 3 groups in total. Group1 has "can read forum" to no, group2 has "can read forum" to no and group3 has "can read forum" to yes. The User1 will be able to read the forum seeing as its part of the group 3 (therefore set user1 as default for group3)
Set your users "as default for group" for the last group that has the highest privileges. This way you'll avoid a lot of headaches down the road. Also, the "never" options only use it if its really necessary. (again this will save you headaches down the road.)

and a nice quick "how to":

To set specific permissions for forums, it?s based on the users and/or groups specific forum permissions.
So for example, we have:
Forum1
Forum2
Forum3
We want to give users Attachment permissions for Forum1, and we will allow staff Attachment permissions in Forum2 -- we don't want normal users to have the ability to attach files in Forum2.
And in Forum3 no user will be able to attach files.
After creating the three forums above. We go to:
ACP > Permissions > Groups Forum Permissions » Select the Registered Users Group. » Select Forum1, Forum2, and Forum3 from the select box » go...
You will be brought to a page where you can select a permission role for each forum listed.
Select Standard Access Role for Forum1, which has "can attach files".
Select Limited Access Role for Forum2, which has "cannot attach files".
Select Limited Access Role for Forum3, which has "cannot attach files".
» Apply All Permissions.
Now everybody in the Registered Users group (which is all members accept for bots) are now able to post attachments in Forum1, and NOT able to post attachments in Forum2 or Forum3.
Now, we want to give the Staff the ability to ALSO post attachments in Forum2.
So let's assume that all staff members are a member of the Global Moderators group.
Go back to Groups Forum Permissions > Select Global Moderators > Select Forum2.
Choose the Standard Access Role
» Apply All permissions.
Now every member who is in the Global Moderators group will be able to post attachments in Forum2 and Forum1 (they are already members of Registered Users, so we only needed to set a permission role for them on Forum2, we don't need to set their permission on Forum1)
