To replace the supply lines for a bathroom sink, turn off the main water supply valve. Turn on the faucets to dissipate any left over water in the pipes. Locate the area where the supply lines meet the main pipe and loosen the fittings. Loosen the fittings under the sink. Put in new lines, insert plumber's tape around the pipes and tighten the nuts. Then turn on the main water supply and let the faucet run for a few minutes to get rid of air.
If the leak is coming from the threads turn off the water and put threadtape on the threads and tighten. If its plastic water lines then turn off the water cut the plastic line and replace the fittings and put a coupling in to join the cut end and the new piece of pipe together, also make sure the pipe is clean when you glue it. That help?

Thaw it out and check for cracks or leaks
Place some towels under the sink to catch any drips while doing this procedure. Turn off the valves under the sink that supply water to the faucet. Disconnect the supply lines to the faucet. Place a bucket under the drain pipe. Disconnect the p-trap. Drop the trap into the bucket. The mechanics of the sink have been disconnected now the sink needs to be removed. If it is a pedistal sink, look for screws or bolts unterneath by the faucet. I've installed in vanity, those sinks are usually glued to the cabinets. Use a prybar to separate it. http://www.lets-do-diy.com/Projects-and-advice/Bathroom/Basins-and-bidets.aspx
that means you might have a leak in the pipes or something.
I generally mount them so the spout is about 3 inches above the sink, but a lot depends on the design of faucet.
Replace the faucet.
One that will hold the sink, faucet, and let you connect up the plumbing. 24" is normal.
You can extend the faucet pipe by, getting an extra metal pipe and welding it with the faucet pipe and it shall be extended.
The plug in a bathroom sink that you open and close with a rod that is in the faucet.
That's what the plug is supposed to do. By plug do you mean the stopper that goes up and down with a pull stem in the faucet? If so, the rod needs to be extended under the sink. They are adjustable.
