Another frustrating question

[Skyline On Fire]

Okay! Well I finally got internet to my outbuilding, running brilliantly via those ethernet wall plug adapter things. Problem is, I want WiFi in here too. I've one Wifi adpater on the roof with a cable leading in, with a working wifi signal, a spare WiFi adapter, two netbooks (xp and 7) a laptop (7) and a desktop (vista) oh and my 360 (irrelevant).

Now.. Using bridges, or ad hoc, or anything similar, how would I turn all this into a wifi network I can use on my phone, other laptops etc etc etc....?

Thanks in advance, as I'm rather stuck.

what wi-fi adapters are they?

if there is one with a cat5 connection get a switch and plug it into your homeplug with whatever else needs to be cabled.
