1999 Land Rover

I have a problem with repairs I have had done at a dealership and would like to know answers to a few questions. 1 If a clutch is very stiff/heavy is it a sign the clutch is going, should a dealership mechanic notice this, when it does go, as mine did, would it be probable that the other bits around it (sorry don't know names) would go as well. 2 If a rear suspension air bag is on its way out would a mechanic know by the sound of the motor for the suspension. In the scenario where bag fails is it probable that the motor driving the suspension will fail. 3 If the handbrake is loose should a mechanic notice this and oil leaking into the handbrake and surrounding area. In short i've spent a total of 2500 in 4 weeks on three separate repairs at a dealership for what now seems like things that should have been noticed before they escalated. I need to know an opinion of a pro before I confront the dealership with my concerns. The land rover discovery on an x reg was given as a gift to me and taken to the same dealership 3 months before this period with the brief to fix every thing necessary before it was handed over. I know this is lengthy any info and/or opinion would be appreciated.
