OK, lets see:
Amazon - hope that works out for you. Unless you buy directly from Bitmain you don't get a warranty.
Would you know 12 gauge vs. 15 gauge wire if you saw it? If so, pull a wall receptical and see how its wired... or better yet, pull both the receptical and the breaker and see if they appear to use the same wire. The stuff you got looks OLD - who knows how many patch jobs were done to it over the years. Still a bit concerned about pulling that much current at 110V, but the receptical should handle it - only breakers have the 80% rule. So yeah, if the wire is good, you should be good. Of course, I'd suggest having a qualified electrician check it out.
220V: Meant buy the plug, some wire, a rig something. Of course, do so only if your comfortable doing so. That doesn't sound like the case, so perhaps ask a friend who is?
1 makes it easier. Its a cheat, but only for the 6 weeks... just buy the plug and wire it to a regular 110V receptical (putting that in a box of course). Test it, and watch it, but running 220V through it will cut the amperage in half. Rather suspect the receptical would handle the extra voltage without any problem. You could even get away with using 15 gauge wire - which is both cheaper and easier to work with. Do keep it as short as practical - under 20 feet would be good. Note that wiring would be simple presuming you can identify the ground lead in the plug. That one gets the bare copper, after that, it doesn't matter which terminal gets the black and which gets the white, since both will be hot (e.g. no neutral). Again, probably best to get a friend that is comfortable building this for you.
Google NEMA standards chart images. For all the common voltages and amperages there is a NEMA specified code - one for the plug, one for the receptical. C13 is what goes into the PSU, other end goes into your receptical.
Actually, using (2) PSUs is not a bad idea, if you happen to have a few laying around - just make sure each is plugged into a different breaker. One PSU powers 1 hash board and the controller (4 PCI-E plugs), the other powers the other two hash boards (6 PCI-E plugs). Do not mix PSUs across hash cards.
No "dorm fridge" or similar setup has the BTU requirements to cool a S9. Sounds like you need to rig ventilation outside - plenty of post showing 6" dryer duct for that purpose. The S9 was designed to be used in an industrial setting, your either going to have to deal with the noise one way or another, there is no easy way to quiet it.
