The router uses DHCP to get an IP address from the cable ISP.

Each of the computers in turn will use DHCP to get an ip address from 
the router.

Ubuntu is set up to use DHCP by default if I'm not mistaken.

There's another method called Link-Local Addressing which is part of 
Zero Configuration Networking, but I don't know how simple this is to 
install on Ubuntu or whether your router supports it.

To share the printer on the local network, make sure that CUPS is 
broadcasting (or announcing) the printer on the local network.

As for backup networking check out this tutorial on file sharing with 
ftp and zeroconf:

There are two ways of handling RAID:

1) Linux software RAID:

2) Installing on a system where RAID has been turned on in the BIOS. 
(FakeRAID) used on systems where you may want to dual boot Linux and 
Windows. Frowned upon in these parts:
