a few noises...

Switching from nissan ester oil to penzoil ultra I noticed quieter overall engine operation, especially at idle. Might want to try a synthetic oil on your next change.

Your second noise just sounds like exhaust ticking after car is shut off. Some do it more than others.

Do you hear a high pitch whine noise at 2-3K rpm regardless of gear? Sounds alot like a supercharger whine. This has been driving me nuts, but is common and normal on the vq37's.

Yea I think I narrowed down the first one to the AC.I notice my compressor makes all sorts of racket when it turns on, I have not heard the knocking noise in awhile. Mine does have a whine after it warms up, but my 08 Z had the same noise, I assume its the transmission just being loud.
