Replaced clutch - does not feel right

[Ali]

Originally when I bought the car the clutch was very stiff, with the info I got from various threads in this forum and also my mechanic the clutch plate, pressure plate and release bearing needed replacement. Just got the car back with the following work done.
1) Clutch plate replaced with new Sachs
2) Pressure plate changed - Sachs
3) Release bearing - ditto
4) Tranmission mounts changed.
5) Lower control arms bushes changed

The clutch now feels way too soft and engages very low on the pedal (car stalls 3 out of 4 times while engaging 1st gear), I have driven manual trannys most of the time but this new clutch just doesn't feel right - bleeding issue ?, going back to the workshop later today to have him fix it somehow.

On the test drive back from the workshop I noticed the steering now has new very strong vibration between 55-65mph (this vibration is there mostly at the steering wheel but also very slight body vibration), still there after 65mph but noticably less.

Steering is very light and has very little feel (read on this forum that steering can be adjusted in some way - my mechanic doesn't know how), feels very dangerous upwards of 70mph, this problem has been there from the day I first drove this car, according to the workshop the power steering is not adjustable and they suggested I look for a used steering box.

Guys your help will really be appreciated.
