I'd say just bright indirect light while they're under the humidity dome. Direct sun can really heat it up under the dome. Once the dome comes off, a little direct light shouldn't hurt. Again I stress, they do need a lot of light to do well, especially thru winter when days become so short. Expect fading of colors with less lighting. They'll brighten up when they get back to the sun. Additional fluorescent lighting helps a lot.
Regarding where to take cuttings, I'd try several different ways and experiment to find which you prefer. I think I prefer tip cuttings, but occasionally I plant a "Y" at the soil line.
