Type your VIN into one of the online ETKs, such as RealOEM or bmwfans.info, and you'll get the part numbers. All E30 front brake hoses are the same, and are readily available aftermarket, but the little U shaped clips that locate them are probably BMW only.
Can't advise on the spark plugs without knowing the numbers on them, but four electrode spark plugs do not work well in a M20 engine. They should be Bosch W8LCR or equivalents.

The Bosch plugs you've taken out are not suitable for this engine, so it's likely they are too short, rather than the new ones too long.
What's the numbers on the old plugs?
Edit: I've just looked back at your first post, and can see what has happened. Your car is from 1992, which is after the introduction of the M50 engine in the E36.
The parts selectors used by the likes of ECP, GSF, etc. assume that a 2.5 '92 3 series is an E36, and it's very likely that you have M50 plugs fitted, for which the 4 electrode item is ideal.
When ordering parts for your car by date, don't go newer than 1990.
