2005 accent clutch? not sure

Hi, I have a 2005 accent with a 5 speed, it has about 80,000km on it.... mainly city driving. Lately, once the car is up to temp. as I pull away from a stop the car makes a loud noise and I really need to feather the clutch out. The noise continues after shifting into second gear ,but no other gears. Thus happens under normal acceleration. If I pull away extremely slow the noise isn't there. If I don't feather the clutch the car lurches like I'm just 'dumping'the clutch and driving like someone who is just learning to drive. Sometimes there is also a whinning noise in second gear if I am accelerating at a normal pace.
Does anyone have any thoughts on where I should start looking? I am assuming it's the clutch due to the fact that it happens after everything warms up. Thanks
