These depend on the size of the composite, the size of the factor base, and the number

2) the threshold for sieving point values before checking it for smoothness
Depends on the number and size of the large primes.

3) how do I choose special q's? outside the factor base?

GGNFS does. I don't.


4) (I'll probably think of more as I go along)

How do I set these parameters?
