Cheesecake that browns -- in the oven too long? Usually a browned top means it's dried and cracked as well. But not always.
Water pan? It's not just a water pan, it's a water bath. The cheesecake tin goes in the bath, and the bath helps to prevent the sides from cooking too fast. The idea is to have the cheesecake cook as evenly as possible. This prevents cracking and curdling. It protects the bottom of the cheesecake from the radiant heat coming up from the oven's floor. In addition, the water pan keeps the oven humid -- a good thing when cooking cheesecake. It also acts as a "heat sink" and helps ameliorate the temperature shifts resulting from the deadband of the oven's thermostat -- again, so the cake cooks evenly. There are probably other reasons as well, but that's what I've got for now.
Altitude? Don't know. Don't be fooled by the name. A cheesecake isn't so much a cake as a custard. Whatever the rules are for baking flan at altitude (speaking of water baths), they're transferable to cheesecake.
Hope this helps,
