SOURCE: two metal pieces are hanging down from the undercarriage

Sounds almost like a motor mount. Have you had recent engine work? Get this checked. If the part is not near the engine, it still sounds like you need to get it looked at.

SOURCE: sound from undercarriage when braking

It could also a slight warp in your rotor that the mechanics missed, (I've had that happen,) the bearings as the above member suggested, or it could even be your anti-lock brake system acting up. Some of the 2005 Cobalts we had as company cars made a funny noise while braking that went away once the ABS got a full fluid change and the dealership reset the ECM.

Oil on undercarriage but none on the ground

It may have been leaking around the oil filter. I would keep an eye on the oil level.

I was pulling out of my drive way and i put my sun-fire into drive and hit the gas and it sounded like something blew i drove down my hill and it progressively got louder, by the time i stopped the car it...

Quite honestly, seek out a trusted muffler repair shop nearest you. They may have to replace if it is too rusted ($100-$150?) or with any luck they can weld it back into place ($25). Not dangerous (unless it falls off) but definately annoying!!

Need an undercarriage protection for our 2003 chevy blazer - cant find one!

There are any number of commercial protection products available over the counter.. of any auto part store, or online.

In my own humble opinion... Your best protection is regular washing with clean water, and some WD40 on all unpainted surfaces. Any coating you put on will eventually trap moisture and contaminants under it, causing corrosion faster.
Easy way to prevent undercarriage rust is to power wash the entire undercarrage, then spray the entire undercarriage with WD-40 before the onset of winter.

WD-40 displaces water, helping to keep rust under control. Suprisingly, it doesn't come off as easily as you'd think in wet winter driving.
Use use two medium size cans of WD-40 to do all undercarriage, making sure to spray every nook and cranny (but avoiding the brake rotors/pads) until it is saturated.

Believe it or not, one good coating will last all winter--at least enough to prevent rust. Each spring, use a high pressure sprayer to clean the undercarriage and reapply a new coat of WD-40 for the spring/summer/fall months.

Sheet of metal hanging down form undercarriage

If you are referring to the front of the car there is a splash pan, designed to keep road spray out of the engine compartment.
and sometimes service people think it was engineered
with two many screws,or they vibrated out.
just replace screws.

if this is not the front of the car please re-post question with more information
hope this helped

Metal piece hanging in middle of undercarriage just behind wheels

It's likely the heat shield for the catalytic converter. There's really no repair for it. Mechanics won't usually spot weld it and they can't remove it. Apart from a little rattle now and then, there's really nothing to worry about.
