Authorization and Client Settings in PI

I'm having NW PI 7.11 based system with ERP6, all on DB2.

Need some clarification for :

1. Are there any standard authorizations that should be assigned to the developer.

2. What client settings / role should be set in scc4 for default ABAP client.

3. I'm running my SLD on SOLMAN.. I dont have a local PI SLD.. I am not sure if I need the PISUPER user on the Solman ?

4. Do we allow developers to access the SLD ? for updating newly created PI z-developments etc ? If yes, do we create an additional ID or provide him with PISUPER password ?

Kindly assist.
