The dracolich is in the Draconomicon and somewhere else, maybe Monsters of Faerun.
And from what I can tell, not really. Any evil dragon can become a dracolich, but dragonblood only qualifies you to use magic items or feats designed for dragons. Since it explicitly doesn't give you the "dragon" type, I would say no dracolich.
Dracoliches do need new dragon-y bodies to possess if they are destroyed however, and a dragonblood creature would seem to qualify for that. So they can become proto-dracoliches, for a short while, before the dracolich takes over.
