I have an 86 eta and I put platinum +4's in it and it ran worse than with the stock old plugs. Get STOCK Bosch plugs. I don't remember the part number, but just your standard plugs and gap them right. BMW knew what they were doing and they didn't skimp on the plugs!
As for coolant, you will hear many arguments about Blue vs. Green coolant. Many die hards will tell you ONLY USE BLUE, it is what BMW uses, so YOU should use it. I personally use Prestone (I THINK...). It does the job, and as long as you use distilled water to mix it with, I don't think you will see too many issues.

Hope this helps!

BOSCH spark plug WR9LS is what you should use. The plat. plugs are a waste of money and dont work well with the older ignition systems. The older ignition systems wont get the plat. hot enough causing them foul out sooner than a normal copper or silver plug.

Blue or green coolant doesn't matter. The blue BMW coolant is a little more refined and lasts longer but the regular green coolant works fine. We use Peak brand coolant at the shop I work at in the older BMW's and have seen no problems and I run it in my E30 with no problems.
