And I need to know why they don't go around devouring everything. Do they move at all?

They do move and some move very fast (but nowhere near fast enough to travel the void between stars in anything but huge timeframes). But this being said sometimes another massive object that the black hole is feeding off, like a neighbouring star will hold it in place, so to speak. But space is just so huge that they pose little threat at the moment, due to the distances involved. Some physists have theorised the existance of micro black holes, that could collide with the earth causing minimum damage, but these have not yet been proven or obversed.
Hope this helped.

They DO go around devouring everything and they do move. But they only "eat up" what comes near them. The ones we know about are those with close orbits to other stars. The bursts of energy and x-ray emissions we see are the fingerprint of black holes sucking in and destroying large streamers of matter their gravity has been pulling off of the nearby star. Nasty things, those.
The closest one we know about is 1600 light years away. There could be others closer, though, but we don't know about them because they are not interacting with a lot of matter.

Actually no one has ever seen a cosmic black hole, however since the Universe is a dynamic system , it is implied that every thing in it moves,including all the galaxies which are moving relative to a dynamic Universal barry center.
If black hole would be real existence they could never exceed the speed of light.

Yes, BH's move around our Galaxy just like any other object.
BH's do consume as they go BUT they only consume what comes inside their 'Event Horizon'. If you remain outside this 'barrier' then the BH is just like any other object. ie if our sun was replaced by a 1 Solar Mass BH then other than the fact that we would be permanently in the dark and no solar wind/particles etc, the solar system would keep doing what it currently does - no planetary orbits would be affected etc
But it is possible for a BH to have a Binary star companion and although that star may be outside the 'Event Horizon' the barrier may be inside teh stars Roche limit thus allowing the BH to accrete material from the star and form a hot Accretion Disk and polar jets (one of the methods of 'seeing' a black hole)

because they are the remains of a massive star and all stars orbit the center of a galaxy. so the black hole would continue that orbit. so the only way a black hole would "devour" something is if it was already on a collision course with the star that created it.

I don't think so. Black holes rip the space time continueum (pronounce con-tin-U-um). If they moved it would leave a gaping hole in it. I think they stay in one place and just devour the stuff that comes by.

I have seen some pretty crazy "black holes" in my time...and they usually devour everything in sight...including your soul!
