Need help to organize this small network

Specs: Windows XP
This is the first time I work with Cisco :-( Our small company is now part of a bigger group and we've moved to a new office. The switches came from a different office (they were configured by an outsourced IT company).

We have the following:
1 Cisco 3560g (24port)
2 Cisco 2960g (7 port)
1 DLink DES-1026G 24+2G
Firewall ZyWALL USG 200

Internet IP connection 2mbps/2mbps with a Cisco 878 router

We have no servers for the moment.

I need like 45 clients connected to the same LAN and provide internet to all of them. What do you suggest?. I guess I'll have to reset the Cisco switches to the factoy settings to clear all the VLANs and start from there.

I guess I'll have to connect the router to one port of the 3560g and then up-link the 2960s and the DLink.

The problem is that I'd like to seggregate from the LAN 6 computers that are old and can't be updated (they run Windows XP with SP1 and can't be updated due to the old software we run on them). I don't know how to do it, can I use 2 different VLANs?. We use a NAS disc, these 5 computers should get access to the NAS disk but not to the rest of the LAN and the rest of the LAN should get access to the NAS disk but not those 5 old computers.

If they are on a different VLAN how they will communicate with the other VLAN and get internet access?. I don't believe I can add computers/printers linked to the DLINK (unmanaged switch) to any VLAN right?

Any help would be greatly appreciated.

Thanks for reading it.

You need to know:
how many external IPs there are & which is yours.
how many internal subnets exist & if each switch is using separate switch.
what wall jacks go to what switch.

Thanks guapo,

I know my external IPs, the ISP gave us a pool of 5, and we are using one of them for the internet connection.

I have mounted the rack and punched the patch pannels, and I have already connected the IP access to the firewall (I use it as DHCP server), and several clients to the network (using the Cisco 3560 and the DLink) and they are in the same LAN and hace Internet access.

There are several VLANs, but some ports of the 3560 have weird (to me) configurations... I guess I'll reset the switch tomorrow.

I'd like to have 2 VLANs but I don't know how to connect them both to the NAS disk, and provide them both internet access.

Why don't you just add the rest of the clients to the LAN that uses the Cisco 3560 and the DLink?
