It would help if you post the configuration you are currently using on the 3560 switch.
Assuming both VLAN interfaces are up you should be able to ping the VLAN interfaces from a host on another VLAN. Do you have 'ip routing' enabled in the switch? Verify this by doing a show ip route in the switch.
As far as disallowing the servers on VLAN 20 from not talking to servers on VLAN 1 you may be able to do this by using ACLs.
No, the ports connected to hosts don't have to allow the other VLAN i.e access port on vlan 1 need not allow vlan 20 traffic. The switch should route traffic between the VLANs.
Can you make sure the hosts aren't assigned IP from the wrong VLAN block? Make sure the IP/Subnet mask is configured correctly and the access ports connected to servers are on the correct VLANs. Little things like could very well be the problem. If you are using public IP addresses the post the VLAN IP addresses by hiding the first 2 octects.
