about the ticking i dont think the change in oil will make it worst. i had ticking every morning but when i got boosted and started using royal purple full synthetic i have yet to hear any clicking noise. i dont wanna say its cause your using sythetic blend because its not. so im gonna say im not sure on that other than when i started using this oil my ticking was eliminated.
for the whizzing noise only appearing on acceleration could possibly be an exhaust leak somewhere.
i havent heard of any common trunk leaks. check the weather stripping on the trunk to make sure its not damaged and the only other place might be behind the taillamp assembly where the harness goes through.
good luck.
