If I have a setup on the network and I there is another on the 10.0.0.x network and want the two to communicate, is it necessary to have a router in place or is there another way using gateway addresses?

    Yes, to have 2 different networks, in this case private ones, you need to have a router or firewall of some type to allow them to talk.  You could use 2 NIC's in the same PC, giving each an address on the respective network.  Then the PC will act as the router.

    Routers can be $10 or $250,000+.  Not all routers are created equal though.  So, depending on the type of traffic and the size of your subnets, your router should be matched appropriately.

    I have 5 hosts connected to my server and there are at most 5 on the other network. I also have the Linksys Wireless-G ADSL Modem Router w/4-Port Switch where my LAN connects. I so going by the advice already given, should be able to communicate with the other network, but I'm not sure how to go about doing this.

    This diagram might help (I think I remember your network from previous posts):

    ISP <-------->Router with switch and Wireless G
                           |      |      |      |
    192.168.1.n      |      |      |      |
    connections      |      |      |      |
    wired/wireless  |      |      |      |---------------->Next Routing Device
                                                                           |    |    |    |    
                                                                           |    |    |    |     These connections are 10.n.n.n network
                                                                           |    |    |    |

    Now, the "Next Routing Device" could be a PC with 2 nics running routing software or it could be another router.  I'd recommend another router.  Just by way of explanation, you could do all this with one routing device, but it would have to be a much more capable router (and probably wouldn't have wireless capoability).
