What do I fix first?

[willrev]

Can't sleep. Just got back from the mechanic. Out of curiosity I took my car to a different mechanic to have some minor work done. He seems honest and fair and had at least twenty 240D, 300D and 300SD and other 123 and 126 cars on his repair lot. I asked him to make me a list of what needed attention since I have only had the car 6months. Here goes. What do I fix first?? I am mechanical enough to do most, but still need to buy a vacuum gauge and a floor jack.

He says the oil cooler hoses look like theve been replaced but they are definitely leaking where the rubber hose meets the metal crimp down at the bottom of the radiator. Oil puddle on my driveway and on hoses. To replace I was told would have to jack up engine and take loose from left motor mount at about 5 hours labor. Don't want a broken hose! Blown engine! YIKES.

The oil filter housing gasket to engine is leaking a little. Front seal in power steering pump is leaking. He suggested a used pump. My fluid was low by 1 1/2 inches. The vacuum pump housing gasket between pump and engine is leaking. He said to fix this and front crankshaft seal at the same time which is leaking oil. I consume one to one and a half quarts per 3000miles.

Turbo tube drain gasket is leaking a little. The crankcase breather drain pipe is leaking oil and may have a broken bracket which could vibrate this pipe and damage air filter bracket.

Rear end is sitting low - he says becasue rear shocks are leaking fluid. He said to replace them, the rear seat has to come out or the fuel tank has to be dropped. He reccomended the Heavy Duty Bilsteins to go back. My car was hit in the left rear quarter panel before I got it. The rear sway bar is close to the spring stop becasue of this, but not hitting or causing any problem, but the HD shocks my raise the height back enough to improve this. His estimate to fix it all parts and labor was parts$486.26 and labor $900. I want to go ahead and fix the oil cooler lines. Can anyone give some directions for DIY?
He replaced the vacuum switchover valves on top of my valve cover and did a vacuum check on the regulating valve on the tranny and adjusted the modulator two turns. My rough downshift is gone, my upshift is the smoothest it has ever been. But he did say the vacuum test on the regulating valve on the injection pump showed this valve is probably going bad, but is ok for now. He said whoever had been trying to adjust the tranny before was doing so without changing the bad switchover valves and thus causing more problems.
