Hmmm. You could have a few issues! The power issue could be a few things, has it been serviced recently?
Check the normal service items first, air & fuel etc. Could be an egr issue especially if the manifold was very sludgy. You could have a lazy injector. Might be worth a bottle of redex and some decent fuel. Are there any signs of overheating? The whining could be various things. Where is it coming from? does the noise change with speed? have you got a dog in the back? Is there any difference when you depress the clutch pedal? could be a release bearing on its way (crap design). Is there any change when you brake? could be a wheel bearing.
