Please Help.Need Advice!

I want to start off by saying hello to all fellow forum members.My name is Chris and i currently drive a 1992 nissan 240sx convertible.The car has been in the family since '94 but for a few years the car was not driven(brother crashed it in '03).My dad fixed it up and have been driving it on and off for 4-5 years.
I finally took it to the dealer last week to get my headlamp fixed(hasn't worked for years)and when they did their multipoint inspection they recommended the following services:

1.Diagnose brake system light(brake system light illuminated)-cost:$107.00
2.Replace control arm bushings(worn/loose)-cost:$519.00
3.Replace rack and pinion assembly(leak at rack and pinion unit)-cost:$689.00
4.Engine oil leak-cost:$1,280.00
5.Rear differential fluid exchange(fluid level low)-cost:$109.00
6.Replace all drive belts(damaged/cracked)-cost:$170.00
7.Replace rear shock absorbers(shockers leaking)-cost:$469.00
8.Change auto transmission fluid exchange(contaminated/burnt)-cost:$190.00

Now,I don't doubt that it needs all that work.Besides basic maintenance,my dad and i haven't done much else to the car.My question for you all is,are they charging me a fair price?overcharging?Could you guys give me average prices for what each item usually cost to fix?Even if thier estimates are fair i still plan on negotiating the price down.

Thanks in Advance

There is a reason people call them "stealerships", why not do the work yourselves, thats honsetly $500 in parts compared to $3800, you wont get that out of a stock previously wrecked car, you may get $2000 out of it if its CLEAN.

^ They tried doing that with my Mom's Maxima. I ended up saving her $1500 worth of bull. With $3,800 tab you can swap another engine and some lol. Do the work yourself if it all possible. With parts + buying tools you still won't come near that amount.

Don't go to the dealership. Other small reputable shops can do it at much cheaper price. 240 is really easy to work on, so they won't charge a lot. You know I've done everything except #1 & 3 by myself. I didn't know anything, but learned everything online. Welcome and please post in vert forum as well.

haha 107 bucks to diag the brake light, its either a bulb out or low fluid if you dont have ABS, lol
