solid hoods can vignette at wider angles
petal hoods aren't as good at stopping flare as round ones are
depends on your lens length tbh
oh and it always goes on widest length e.g. a 27-70 has a hood that won't vignette at 24mm but won't be as good at stopping flare at 70mm

Tried one on my Canon and kept getting pictures of feet with no flare. so work perfect if your not Samson

Not true that petal hoods are not as good - they are actually better! Unless your photos are circular.
The best hood is rectangular, exactly the same shape as the image frame. And as big as possible, so long as it doesn't protrude into the image area.
A custom petal hood is effectively a rectangular hood from the len's point of view, but is easier to store reversed on your lens. Easier to manufacture as well.
Another aspect of the focal length thing is that hoods for full frame lenses are not as efficient as they could be when used on crop fromat. They are designed not to encroach into the image area of full frame, but when used on a crop camera they could usefully be made a bit bigger. Hoods for EF-S and DX lenses are better in this respect.
I always use a lens hood. They do improve image quality in difficult light, and they are good protection. They work just like the sun visor in your car

Hey kid! Petals are great
On the learning thing, photography is not as difficult as it seems. This article covers the basics, Understanding Photography http://www.talkphotography.co.uk/forums/showthread.php?t=99841
Don't worry about the technical stuff if you're a beginner. Just put the camera on auto and concentrate of finding the right angle and good framing for your photos. Then note what the camera is doing, and how it affect the final result. You'll soon get the hang of it and then begin to set the controls yourself.

If the front of the lens rotates in focusing, then obviously you can't have a petal hood, eg hood for Canon 18-55 kit lens is round, but hood for 17-55 2.8 is petal.
With longer lenses, you quickly get to the point where extra length or a more efficient shape doesn't do much. In fact it just gets in the way. So just keep it as long as it needs to be for efficeint shading, and no longer. It's a convenience thing. On a 400mm lens I guess it would be possible to fit a lens hood about a foot long without it vignetting the image, but the last 6-8in wouldn't contribute anything useful.
