Sounds like you have quite a few problems. If you have to keep changing the fluid , you must have a heat problem. If you are having noise and difficult shifting and grinding gears could be an alignment of the trans to the engine block or engagement/ dis engagement problem which leads us to another problem you talk about with the travel of the pedal. and that you don't have your components matched correctly with the clutch slave and master cylinders or even line size and material.
