Thanks.
Not all turbos have water lines, but the water cooling helps the bearings stay cooler makes them last longer. Most stock turbos will have water lines for that reason, and most good aftermarket turbos do too. Turbos need to tap off of the engine oil system, else you'll have to add a oil pump, oil cooler, and tank for the turbo. There really isn't any need to do this just to lubricate the turbo, and the amount of heat added into the oil is a very small fraction of what the engine produces anyway.
