Front-End Rattling/Buzzing

[Fluffizillamon]

Part one: So when I'm driving along, it sounds like both my front tires are wobbling in the ends of their axle. My alignment is spot on, though, and the steering is tight. That noise just makes me nervous. Does anyone know what's probably causing it, or a simple/cheap way to find out? If you know what's causing it, what will it take to fix it or is it worth worrying about at all?

Part two: The buzzing noise happens mostly when I'm accelerating, and it sounds more like it's coming from the rear of the vehicle, and it only lasts a second. It sounds almost like it's just a loose piece of cosmetic plastic vibrating or something, but something tells me it's not that simple. Any leads as to what might be doing that?

Part three (the bonus!): Sometimes when I start my car and put it in gear, it makes that awful squealing noise, which I'm sure everyone knows, for up to a minute. This usually seems to happen when I haven't driven it for a day or two. What's actually making that noise, is it a problem, and how do I fix it?

Thanks in advance for any and all feedback; this is the first car I've had that seems in nice enough shape to begin with to put a little extra work into it to keep it in top condition. If there are any general tips for increasing efficiency and reducing as much wear-and-tear as possible, I'm happy to have those too.

Part one: Inspect end links and if needed, replace.
Part three: Replace alternator belt and tension the new one correctly.

Okie dokie; what's the best way to know when my alternator belt is properly tensioned? The internet at large doesn't seem to have reached a consensus.

I replaced the front end links. The handling is definitely a bit tighter, but the rattling isn't completely gone. What's the next suspect I should bring in for questioning?
