Much like solar-system formation. That black holes 'suck stuff up' isn't entirely accurate either. An accretion disk vs. stellar disks vs. flattened spiral galaxy disks... Hmmmmm...
The first generation of stars would have been HUGE wouldn't they? With all that hydrogen and helium to draw on wouldn't stars start to form shortly after the 'end' of the dark age? Wouldn't they all form on these irregularities or fluctuations presented to us in the CMB? Wouldn't they have lived short lives, resulting in spectacular bursts of gamma rays and million or billion solar mass black holes? Wouldn't they have created enormous amounts of heavier elements?
Do I ask too many questions? Or what?
[edit start]
Any supermassive stars would go superdupernova and compress the surrounding hydrogen to create a new batch of baby stars that would then begin to orbit the newly created supermassive black hole! Man I'm good!
