Bringing our US electrical devices to the UK / also NTSC-PAL question

It's generally advised to leave as much behind as possible when moving abroad, but my wife's employer is paying to have a decent amount of our household stuff transported from the US to the UK. And why would we want to waste money buying duplicate items if it isn't necessary and we probably won't be staying more than a couple years? So I'm trying to figure out which of our electronics and appliances might be made to work overseas. I am aware of the voltage difference and the line/mains frequency difference between the US and the UK and I'm considering buying one or two good-quality step-down voltage converters for things that aren't universal voltage compatible. But I have some questions that my Google research has not cleared up. [more inside]

Electronic Catan

I want to create a customized Settlers of Catan board. For the purposes of this question, it could also be a custom Monopoly board. I want the pieces ( cities / hotels ) to light up when they are placed on the board. I know I would put LED's in each piece, but besides that, I am not sure if or how I could power up the LED's. I am not an electrical engineer, but magnets, watch batteries or inductive charging sound good to me. Help me make an awesome electronic board game!

How do I reduce static electricity in my house?

Carpets in new home are producing tremendous amounts of static and lots of sparks. What are good solutions to reduce the static to protect computers and other electronic equipment? Ideally, the solution would reduce the static across the entire house, as trying to protect each piece of equipment with an anti-static mat or some such would quickly become cost prohibitive.
