As for IP Addressing, you may want to look into your DHCP server to see if you can make reservations for devices (most recent routers will accommodate this) so they always get the same address, this would be done by MAC address. I do this in most installs due to the fact that you add or change something in the network you do not need to go to all the devices that you have on the network and make the change, now you just make the change on the DHCP server and it changes it on all devices. Plus with the reservation you always know the IP Address of each device and you know the MAC Address which a lot of manufacturers use as serial numbers.
