For lighting, check out the Magicshine model. It's a LED light that comes with a rechargable battery that lasts ~3hrs on it's brightest setting. The lighting section this site should have plenty of info on it as it's a pretty popular light due to it's brightness/cost (I spent -$100 on mine). I do all my riding at night and I love this light-really happy with my purchase. I would not mind a investment into a dyno hub, but, that's a big step up in cost.
