You can say that again! You should see some of the messes I've had to clean up over the years.
I agree with ace_omega. My initial look at the images you pasted the links to, especially the close up of the panel, looked to me like all 8 wires were terminated. Plus, the panel itself was color corded for the 4 pairs, Blue, Orange, Green, Brown.
I just looked again now and it appears there's also space to punch one more pair on each but from what I can tell, nothing is punched in those slots.
You never did answer my question about whether or not that panel has RJ-45 connectors on it. Does it?
I still say, your best bet is to buy a 12 port patch panel and punch all those cables on to it. After testing the lines to verify they work, you could then build a small shelf to hold your modem/router/switch and mount it on the wall under your patch panel. Then just run cables from the PP to the switch, connect the switch to the router and the router to the modem and you'll have a LAN and external (internet) connectivity to each outlet.
