1- i want to devide the segments in to 4 vlans. what could be the possibilities of the vlans addresses( Vlan1 should be what about the rest.
2- how can i configure Inter Vlan comunication in this switches ? as the document provided with the switch doesnt really crarify how to do that. Step by step guide is highly appreciated.
3- how to configure DHCP relay ( is there nay further options to configure for a Windows 2003 server to act as a DHCP server, is there any thing i should do/add in the Switches configurations?

1. If you are managing the IP addresses for the entire enterprise you can use any of the private addresses subnetted to suit your needs. So,,and would be a good set assuming /24 is enough for your VLANs.
Private addresses are: – – –

2. To route amongst VLANs on a layer 2 switch like this you need to have an external router with a physical or logical interface in each VLAN. A router on a stick config is common  in this application with a single physical interface on the router connected via a tagged link to the switch. If that is the case here you would make a tagged subinterface for each address range and connect it to the switch on a port that is also tagged with each of your VLANs.

3. For DHCP relay you need to enable it globally, create a group with a list of the dhcp server addresses and enable it on each VLAN's IP interface you want it on.

Another issue, when creating the vlans and choosing the ports allocated for each vlan it asks me to choose if the port is Tagged or untaged! I'm not really a pro in this area, so wat should I choose! And the same thing for the vlan interface port should it be tagged or untagged!
You would use untagged for any ports that go to non-network devices like PCs, Printers, and servers. Tagging would only be used on ports that go to a router with multiple subinterfaces and vlans configured or switch to switch links that have multiple VLANs.
