Default 2008 Touring Clicking/Knocking Sounds

I know there has been probably a good couple thousand of these threads. But please do bare with me.

I'm used to driving a really crappy 1996 Dodge Dakota, it made all sorts of very bad sounds. So any sound I hear on my Z, I get extremely paranoid. I recorded a few videos regarding the 2 sounds that I'm hearing. I know video aren't a definitive source. But I'm just hoping for some basic input from experienced Z owners.

The clicking sound, I've read all sorts of things regarding that. But from I gather, the clicking sound, regardless of the issue, isn't an issue at all. The slight knocking/thumping sound is my concern.

During cold starts(@26F and below) I hear the knocking/thumping sound on the right side of the engine, towards the upper back side. When the engine is nice and warm and has been driven, I hear the sound same area, but more present underneath. It will also idle, what seems to be in my opinion, roughly, and when I'm against a wall, like at a drive-thru, the engine seems loud, kind of embarrassingly loud. Is that normal?

Once again, I'm used to driving a really crappy truck, so I just want to be sure I'm not being overly paranoid/protective of my car. Thank you!

Also! I don't think I did a very good job explaining the issue in the video, I'm sort of retarded on camera haha, so please do read this wall before watching the video, and listen for the slight knocking sound.

Links below for the videos:

I should note:

The car is used, I purchased it a little over a month ago. I don't know the cars history at all, other than the very crappy carfax I bought. It seems like the person before me took care of the basic maintenance. I bought the car at 101k, and now the car has 108k. I changed the oil and oil filter 1,000 miles ago and used full synthetic(for now).

tl;dr

Car is making knocking/ticking sounds under the hood. Watch video
Car is a 2008 Touring Edition used with 108k miles

What's the oil pressure at idle and 3K rpm's when the engine is fully-warmed?

Idle is between 15-20psi, I don't remember 3k, but after 60mph my oil pressure matches my speedometer it seems.

Those numbers are OK, if the gauge is working correctly.
