2007 Subaru Legacy Engine Mounts and Prop Shaft?

[wldl5]

Hello everyone,
I recently bought a 2007 Legacy as a project car, and I’ve run into a few issues while driving it.

First, there’s a whirring noise coming from the middle rear area of the car. The sound changes with vehicle speed. I watched this video (the noise is very similar):

@ 1:40. However, when I was under the car, the prop shaft didn’t seem to be making as much noise as in the video. The wheel bearings have already been replaced. Is there anything else I should check before I go ahead and buy a new prop shaft?

Additionally, I suspect the engine and transmission mounts may need replacing. I took a video from underneath the car while shifting through gears (

), and the engine/trans assembly seems to bounce quite a bit. Is this amount of movement normal, or do the mounts need to be replaced?

Thanks for your help!

, for the past few months, I've been hearing a slight...rattle, I guess you could say, that's only audible from inside the cabin. If I give the throttle a sharp tap (as opposed to smoothly depressing it)
