1996 Bmw 740 Il

I just bought a BMW 1996 103K Miles on it..have noticed following problems.

1. Steering wheel is shaking initially at low speeds..
2. Monroof Lower Fabric flab is not retracting when pulled with hand..but is retracting with the Moon roof when I switch on the button..
3.Audio is crappy..when I increase the volume..the speakers are bad...


any suggestions are appreciated...
