If the taps and the spout are not connected in one unit, the spacing on your sink is probably 8 inches center to center. The only faucet I have seen for a bathroom sink with that spacing is the two handle type. There may be a single handle available. A kitchen faucet may work if the holes in the sink are large enough. Kitchen faucets are 8 inch also. If yours is 4 inch, then it is no problem, they are common.

That would depend on the height of the drain and how deep the sink is. As long as the drain is lower than the bottom of the sink, it should be fine.
Install a ty fitting on the stack in the basement then run it to the sink. Put it low enough to account for a fall in the pipe, to allow proper drainage. Be sure to install a waste and vent pipe to code for both fixtures.
We don't know the proper condition of plumbing at our home and many times we face some problems related to sink or toilet dirt.The reason behind this is the improper working functionality of pipe blockages due to some dirt or garbage material stuck at the pipe line.So always make sure that the proper water supply from all pipes and remember the 'smell' is the indication of pipe blockage.
For a standard 30"- 34" high sink water lines are typically stubbed out of the wall between 16"-30" depending on the sink itself and rough in dimensions(if applicable). That does not mean that they can not be at another height, it really has to do with the sink and application layout.

About where your belt line is. Ideal height will vary with the height of the person who plans to use the sink most often.
