Does anyone here know the approximate ammount of output from a BBS
PRNG needed to predict with some certainty the next bit or bits? - is
the generator totally secure, ie. do you need to factor to predict or
is there an attack using the output?

The whole point of a BBS generator is that you have to factor in order
to predict -- I'm sure that Schneier has a discussion on this.
