Resource Mangement question(s)

Question

Hello,
I'm running Oracle 11.2.0.2 (on Solaris 10).
I'm reading an Oracle whitepaper on Resource Management and hoping someone has experience with this subject.
Re: http://www.oracle.com/technetwork/database/performance/resource-manager-twp-133705.pdf
I have gone through the steps in this paper in attempt to set two different users (actually these are main user accounts that are shared) to two separate consumer groups, but I'm a little lost how to assign them to those groups.
So, here are the steps I've done:
=======================
SQL> alter system set resource_limit=true scope=both;
System altered.
SQL> alter system set resource_manager_plan = 'DEFAULT_PLAN' sid='*';
System altered.
SQL> exec dbms_resource_manager.create_pending_area();
PL/SQL procedure successfully completed.
SQL> BEGIN dbms_resource_manager.set_consumer_group_mapping(attribute => dbms_resource_manager.service_name,value => 'REMEDYT',consumer_group =>'INTERACTIVE_GROUP'); END;
PL/SQL procedure successfully completed.
SQL> exec dbms_resource_manager_privs.grant_switch_consumer_group(grantee_name => 'ARADMIN',consumer_group => 'INTERACTIVE_GROUP',grant_option => FALSE);
PL/SQL procedure successfully completed.
SQL> exec dbms_resource_manager_privs.grant_switch_consumer_group(grantee_name => 'ARRDONLY',consumer_group => 'DSS_GROUP',grant_option => FALSE);
PL/SQL procedure successfully completed.
SQL> exec dbms_resource_manager_privs.grant_switch_consumer_group(grantee_name => 'public',consumer_group => 'DSS_GROUP',grant_option => FALSE);
PL/SQL procedure successfully completed.So basically I'm allowing the main application which uses schema ARADMIN to use the "INTERACTIVE_GROUP", and the schema ARRDONLY (or any other user) to use the "DSS_GROUP".
But, this seems to only "allow" these users to switch to these groups, rather than assign them to these groups.
Also, how do I see (or adjust) what allocation of resources are given to these groups respectively by default.
These are all Oracle default groups.
I'm a little lost on this one whereas in the past I've just considered to use profiles for managing resources, but this is different, (and perhaps better for what I'm wanting to accomplish). What I'm wanting to accomplish, is exactly as noted in this whitepaper:
You can also use Resource Manager to explicitly allocate CPU resources to the multiple
workloads or applications that are sharing the database. For example, you can prioritize
“sys” over regular users and OLTP transactions over reports and batch jobs

dbms_resource_manager.service_name
Also, how do I see (or adjust) what allocation of resources are given to these groups respectively by default.You need either to create a simple plan using CREATE_SIMPLE_PLAN http://docs.oracle.com/cd/E11882_01/server.112/e25494/dbrm004.htm
or a complex plan using differents steps described in http://docs.oracle.com/cd/E11882_01/server.112/e25494/dbrm005.htm.
You can query following dictionary views for resource manager allocated resources:
DBA_RSRC_CONSUMER_GROUPS
DBA_RSRC_IO_CALIBRATE
DBA_RSRC_PLAN_DIRECTIVES
