I think I would also start a thread on the W203 forum so you capture the attention of some other actual owners. Whoever sees your thread here is hit or miss. I own a different car and the other poster probably does too. Back to your problems now.
SRS Light could also be due to a bad weight sensing pad in the passenger seat. It's purpose is to sense the weight of the person sitting there. If under about 60 lb it inactivates the airbag.
CD player/changer is one of the components that are connected to others in the D2B fiberoptic loop. If it is not recognised by the car, it can malfunction. If this is the problem it will take a dealer, or someone else with the Star diagnostic system to code it into the car's system.
Windows might be due to liquid having been spilled around the master switches. At least on my car, they are connected together on a single circuit board and under the center console.
Horn might have something to do with the steering wheel since that's the only place I know of to activate it (make it blow). I have never had one apart so I don't know how close the +/- button wires are to those involved with the horn.
One last thing is your car has a CAN/BUS system that links certain components together. I don't understand it at all but it has been blamed for any number of strange electrical-type problems like with the bad battery I mentioned earlier.
