Stop Staring!!!!!
Internet --> WAN port on the BEFSR81. Make sure DHCP is on with a range starting at x.x.x.3. DHCP example - 192.168.1.3 - 192.168.1.254. Have a LAN IP of x.x.x.1. LAN IP example - 192.168.1.1
Any available port (1-8) on the BEFSR81 --> any available port (1-4) on the WRT54G. Do not use the WAN port. Turn off DHCP. Have a LAN IP of x.x.x.2. LAN IP example - 192.168.1.2
Any available port (1-8) on the BEFSR81 --> any available port (1-5) on the ESH-705. No need to set an IP. Just PnP.
Not sure about the ESH-705, but you should be able to connect the two routers with either a straight-through or cross-over CAT5 cable. It's likely you'll need a cross-over CAT5 for the ESH-705.
I have been working on this for a bit now. Seems much better. I have the BEFSR81 & WRT54G running. Everything Seems OK. Also the Wireless portion is going strong. All that is left is to try to work the ESH-705 up.
