This is a quick summary of really common bitmap and vector file types:

Bitmap Vector
.bmp (Windows bitmap) .ai (Adobe Illustrator)
.jpg (JPEG) .cdr (Corel Draw)
.gif (AOL Bitmap) .eps (encapsulated postscript)
.tif (Tagged Image) .ps (postscript)

As you've seen, vectorizing graphics provides tremendous benifit when the difference in size between the original file and the desired output size is huge. It's not such a problem if only small resizes are required.

Lastly, here are a couple of graphics that I've vectorized from client-supplied bitmaps. Both took around three hours.
