"He was a straightforward sort of bloke, no bullshit about him. Of course his kind of confidence often came with money, especially a) money that was not just drawn out of the gene bank, b) not hereditary money previous generations had stashed away."
1. What does it mean by saying no bullshit about somebody?
2. Are a & b talking about the same thing?
"No bullshit about him" means he spoke directly and plainly and to the point.
As for A and B: it may be that A is intended to imply "money that was earned simply by his natural attributes", as opposed to the inherited money of B.
For instance, you might (perhaps unfairly) say that a supermodel draws money out of the gene bank, since her money-making appearance is a product of her genes.
