Mitsubishi Space Star gearbox? driveshaft? grinding noise

Hi all, i drive a mitsi space star glx gdi 1.8 petrol(dont laugh)on a 2001 y plate, my problem is that the car makes a loud grinding noise when in neutral and throughout the gear range when driving, when i press the clutch down half way the noise goes away completley, i was thinking maybe input shat bearing but on inspection ive noticed that the passenger side wheel is realy hard to turn to the point that after a quater of a turn it wont budge (jacked up obviously)and also clicking sound on full lock when driving,also ive noticed a quater inch of play on the vented disc on the same side, gearbox, drive shafts,hub problem i dont know? any input would be appreciated, many thanks Andy
