My Question : Is the above topology work? The access points register to the controller via 2960B, and the data traffic ffrom wireless clients go through from 2960G B to WLC port 1, and WLC pass it to port 0 itself and then go to internet?
As long as you don't have LAG enabled that will work. You do need to specify a dynamic interface in which the Internet traffic will egress. Your management will be primary port 1 and the your dynamic interface will be primary port 2. Of course port 1 and port 2 would have to be on a different subnet.
If you have both on the same subnet, that will not work. You would trunk the ports and only allow the vlans for that port. Port 1 connected to the switch would only allow the vlan for the management. Port 2 connected on the switch will only allow the vlan for that dynamic interface.
Well there is a right way of doing it and a bad way of doing it. The easiest and prefers way is to enable LAG on the WLC and connect to to one switch in which the WLC is connected to a trunk port. You really need to k ow how things flow and what works and what doesn't work when you start to separate ports. If you don't understand it, it's very hard to explain in a forum. Take a look at this startup guide and try to get it to work the normal way.
