Here's what goes into my '01 A4 1.8TQ manual:
engine oil: Mobil1 0w-40. I believe the owner's manual actually recommends
0w-30 though, but unfortunately M1 0w-30 does not meet the ACEA A3 specs
which are also called for in the manual. That's not to say that M1 0w-30
won't work. Other good synthetic oils in the US): Redline 5w-40, Amsoil
0w-30, Castrol Syntec 0w-30 (but only the one that says Made in Germany on
the back label since it's actually the European Castrol SLX - hard to find
transmission oil: GL-4 spec (not GL-5). Something like Redline MT-90
should do fine or just stick with the Audi OEM fluid which is apparently
also very good.
spark plugs: NGK PFR6Q
