Fluid lean on/near the clutch peddle is almost always the Clutch Master Cylinder. Replace with Motorcraft part.
Lack of power could be a few things.
The 'steady acceleration' to me says that it may be a problem with the Throttle Position Sensor or the Mass Air Flow Sensor. Both should throw a code if there is a problem (check engine light). But sometimes the light won't illuminate. Best bet is to use a scan tool and check for codes through the OBDII port (bottom of dash near the hood release).
If any codes are found, write them down and post back with what they are.
Go from there.
