Corsa 1.0 12v GLS problems (stiff clutch and accelerator)

Just bought a 'w' reg corsa for my daughter and I must admit when I drove it
I thought it needed a bit of TLC engine wise.
The clutch is very stiff and bites about 2 inches from the floor , is this a
sign the clutch is on its way out , or can the biting point
be adjusted to nearer the top ?
Also the accelerator pedal is really stiff and there seems to be no result
from pushing it down for the first 2 inches , is this adjustable
or needs the cable oiling . The last point the car idles at 1600rpm and
stays idling at this speed even after warm , what is this likely to be

Thanks
Jim

 

Also can the drivers seat rails be adjusted at all , she is small 5" but it
seems that there is not enough
travel to get the seat far enough forward , without having the seat height
adjusted all the way to the top.
So she is always at full stretch which makes driving uncomfortable

 

Regarding the clutch, as the spinner plate wears, it gets thinner. this
causes the contact ring in the clutch cover to travel nearer to the flywheel
to maintain contact. Because of this the thrust bearing will move away fom
the flywheel. (when you press the pedal the thrust bearing moves toward the
flywheel to disengage the clutch). As a result the pedal-and the bite
point-will slowly rise as the clutch wears, assuming a cable system and not
a hydraulic one. (intrestingly enough, my old mk1 cavalier 1.9 had a switch
on the clutch pedal that lit the handbrake light when the pedal rose to high
to tell it was time to adjust/replace the clutch. didnt half cause some
confusion!<g>). If the bite is too low, then its one of 2 things. 1-it needs
adjusting, 2- the tongues of the clutch cover have overheated and bent.

oh, brother in law had a citroen bx that did this, but it was a bent
actuation arm. that doesnt count here tho', coz that was a silly french
design..
