Dracaena Massangeana rescue attempt

Help! I visited a friend at his house the other day (first time there) and noticed a plant in the corner with a few brown leaves looking a little sickly. I asked him about it and learned he had received it as a gift several months ago, and really didn't want it. He admitted neglecting watering it enough, and it had been in very low light conditions. So I confiscated it, and suddenly, I'm fascinated with trying to restore its health. After looking at 6 billion plant and tree pictures on the internet, I finally came across a perfect match and determined it to be a Dracaena Massangeana. I've read about a hundred postings about health and maintenance for these plants, but not much on restoration advice. I'm aware now of proper watering and lighting, but I'm not so sure about what to do about the brown dead spots.
So my problems are: 1. There are 3 stalks which appear strong and healthy, but about one in every four leaves is partially or totally brown and whithered. I realize I need to pull the dead ones, but I'm not sure about triming brown from the mostly healthy leaves. Is that possible, or what should I do? 2. Several leaves look healthy in appearance except that the weight of the leaf or mishandling caused the leaf to bend to a fold. Can I splint this somehow until it strengthens, or would this be futile?
Thanks for ANY help or guidance! Feel free to reply here or mail me at technosorceryAThotmaildotcom

Brown edges can be trimmed, but be prepared for further browning.

Splinting won't do much good, alas.
Were this my project, I'd get it back on the road to health, and then air layer it about 6-8" below where the leaves look good. When you have good roots, sever the tops and replant; you can cut the old plant back severely and you'll probably see good new growth on that, too. http://www.ces.ncsu.edu/hil/hil-8701.html http://www.urbanext.uiuc.edu/houseplants/propagation_airlayer.html
