Okay....I think I'd like to approach your questions from a different angle.
Let me be very frank. I think it's not a good idea to mod this car for any number of reasons. First of all, it isn't worth very much and never will be, so any money you put into it will be completely lost to you. Secondly, it is a large heavy car and no matter what you do, it's not going to handle like a sports car. Last of all, the number of mods available to you are limited, since the aftermarket tends to provide more cosmetic and restoration items than modification items for cars like this (supply and demand).
My advice would be to just enjoy the car as it is. If you want a faster, more agile BMW, sell this car and buy yourself something like a 528i or a newer 3 series coupe or even an older 635CSi if you wish.
As for the key question, I don't think there's any kind of chip in there. Your radio code is 4 digits, but if you don't know it you are probably screwed. Sometimes people put the code in the owner's manual or even write it on the radio itself; otherwise, you'll have to figure out something else, an aftermarket unit.
If you go to Google and type in "BMW parts catalog" you will find plenty of resources for your car. I think if you order up some of these catalogs you will see how limited you are in the area of modifications.
So to summarize, if you want a faster BMW, go buy a faster BMW, or start with a car where you are more likely to have a satisfactory result. Otherwise, just enjoy your car as it is.

Another problem, power steering fluid leaking. Shop want replace entire power steering unit. It looks like a hose is leaking. Is it difficult to remove the bad hose only and replace? Looks awful crowded in that area?

Engine runs good. When driving away, I hear a tinkling noise - seems from the bell housing area. Any idea what it might be?

I recently lost the use of my in dash trip computer and the ability to move the rear electrically operated seats. I suspect a fuse has gone bad and I would like to track down the fuse box and the bad fuse. Any ideas where the fuse box for these items is located and what fuse controls these devices?

The fuse box is under the hood, either on the driver's side or passenger side- square box that flips open. Inside, there's a reference guide to which fuses go where and the amperage. You may find either new fuses as any other may use or you may find the BMW original fuses. BMW original fuses are cool because you can just look at them to see which ones are bad rather than pull them out one by one like every other car. Keep in mind, that although they LOOK like they are okay, trust me, the oxidation from the outside environment may have put so much resistance on the fuse to stop it from working properly, even though the circuit is not open. If I were you, I'd just get a pair of needlenose pliers and start methodically pulling each one out and replacing them with brand new fuses (standard domestic issue) rather than the BMW original style fuses otherwise, you're gonna have the same problem again. FYI, also stock up on 7.5 amp fuses because you're gonna need alot of them if you're gonna replace ALL of them.
