You will have better luck with one post instead of two. I suggest locking this one and using -
https://bitcointalk.org/index.php?topic=1101306.0I asked a few questions in that thread. But it appears you put more in here. You would need to look into windows connection sharing and have a hub or something as only one ethernet port.
I don't suggest running a laptop 24x7. I suggest looking at a router that also can as a client to other wireless and share the connection to the two miners. They also make wireless adapters you could make work with a hub. But a router with ability to connect as a client to other is cleanest setup in my opinion.
