Sorry if this has been asked already:
Is it possible to run just wired (ethernet, no WAN)? I tried disabling the WAN hoping the packets would route through ethernet, no dice.

It is possible. You need to reserve a fixed IP address on your home router, then connect the WR703N through an Ethernet port (most WiFi routers come with extra Ethernet ports). The WR703N has a fixed IP address (I believe it's 192.168.0.100). Once you do this, I believe you can also connect to the WR703N though your home WiFi router.
Here's a sample setup:
