Ditto on this your clutch isn't disengaging all the way and dragging between the pressure plate and flywheel.
Unless the clutch is worn and slipping I would just replace/rebuild the slave cylinder so it is traveling full stroke and fully disengaging the clutch.
Hard shifting is because the input shaft is turning from the clutch dragging.
A bad pilot bearing can do this also but general it isn't so prevalent and will make a noise.
Try bleeding the slave and see if this fixes the problem, if it does you have air in the system and may need to replace the clutch master also.
