Home recording studio questions: (1) What to do about sound source with a noise problem (sounds like a bad ground loop) and (2) building some approximation of an isolation booth. [more inside]

(1) I've got a Chet Atkins Electric Classical and a Hughes & Kettner amp combo that I like quite a bit. There's a low hum that gives me pause when recording, though, and it's especially bad if I use the XLR direct out on the back of the thing. I could mic the amp cabinet, but I'm a little bit afraid to do that because the walls/ceiling are sortof thin where I live and there's lots of ambient noise. I'm pretty sure the amp is the problem, as I don't get the noise if I just take the guitar straight into an M-Audio pre-amp (which is probably an audio atrocity, but it works). I thought of trying to record the hum and inverting it and trying to keep that synced with the actual track, figuring superposition would mean I'd get reduced noice. I have not tried a narrow notch filter yet.
(2) So the other things I could do is build some kind of isolation booth. I can't really modify the place, so it has to be freestanding and I don't have a lot of room anyway, so it has to be something I can set up and take down and store without too much trouble. My first thought was a PVC pipe frame around which I could hang some quilts. Any others?
