I have never seen a faucet that has a nut on the line coming out of it. Usually it is a male connection and the nut is on the supply line between the faucet and the house supply. Anyway, if the line coming out of the faucet is messed up, you could probably cut it and use a compression fitting to go between the faucet and the supply line to the house line.
Often there will be debris in the line that clog the screen in the spout. If not that, it may be in the faucet itself. With single handle faucets or two handle that are quarter turn valves, it takes very little to block the hole that water comes through.

That would depend on how many holes the sink has .... If it is a one hole type you will need a pull out spray faucet or look at the Delta line

Call a plumber.
