The way to do this with an L3 managed switch is to use inter-vlan routing and access control lists.
First part is simple enough, enable IP routing in the switch, then give your vlan interfaces an IP address.
To control which nets can talk to others you build ACLs and attach the policy to the vlan. For instance, you can permit your workstation on the main net to talk to anything on nets 2, 3, and 4, and conversely they can talk back to only your workstation if you wish. Then you can deny anything on nets 2 - 4 from talking to each other.
Have you gotten into the RBSU and changed the power profile to "Minimum Power Usage"?
