Possibly you have already sorted this, Matt.. but..
PSU: no problems, just a simple step up transformer will sort that. I can supply one at cost if you are truly stuck for locating one/don't know what one is.
Freq: modern TVs sold in UK will handle NTSC just fine. If you can't get one that will, there are other solutions too, which I can help you with.
Oh, yeah, I am in the Midlands, just so you know :¬)
