Riding the clutch is a term used when you press the clutch half way down and roll forward. here the engine is engaged to transmission only partially. This is where the wear of clutch is maximum.
if the cluch is either fully engaged or fully disengaged then there is no problem.

This is not necessary depressing the clutch fully will give you the desired result of disengaging the transmission from the engine.

Thanks in advance! |
This is not advisable at all. Gear 1 exists for a purpose - to start the car from the position of rest and reach a speed of 10 kmph. At rest the car has high inertia for which we need a lower gear like gear 1 to handle that.
