No adjustment.
Bleeding only indicated for a long pedal or clutch drag.
High pedal points to friction linings which have become hard and non-compressible, there is a wave spring between the two friction faces and some give in the friction material which helps to give some progression or 'feel' on clutch take-up. If the friction linings have been cooked they become very hard and rigid, clutch action becomes very sharp (on or off, no in-between) and pedal is high because no 'travel' is required to overcome the spring and material compression. If the linings are worn to the rivets then pedal is also high (again, no compression or 'give' in the plate) and action is sharp as above but when you floor it in 3rd or 4th on a hill you get clutch slip.
Added: The clutch cover also wears at the pivot points which changes the leverage quite dramatically, this tends to increase the required pedal pressure which is why a new clutch often seems much lighter.
