Chosen answer: In the book, the location of the antimatter bomb is only revealed after the Camerlengo pretends to have a "vision from God" on the steps of the Vatican. By changing the symbol to one that actually provides a clue to the location, it allows Langdon to work out where the bomb is, to actually play some part in proceedings rather than passively stand by until the villain just takes everybody there as part of his plan. As for the Pope being the Camerlengo's biological father, this is a fairly late revelation in the book and requires a substantial amount of exposition, which would only serve to abruptly slow the film to a crawl during the climax. The Camerlengo's motives, his hatred for the church's indulgence of science, are strong enough to explain his actions without the additional detail of his parentage being necessary, thus it could be safely left out to keep the film's momentum going.
