Yes. Books don't change engine settings. At least that would be a very new
feature I never heard of! :)

Yes... the engines themselves are not changed no matter which book you use. The
openings and the positions in which they'll have to start calculating in the
games each though, may be more or less unlike those resulting from other opening
books.

Basically not, but for instance having to play variants from your alternative
book which the engine's book may usually avoid, can result in games of different
character from what is typical for the games, in which the engine's book is
used.

(Different engine moves in the same position can occur of course, due to many
parameters like time, computer speed, hash content, or due to a learning feature
which some engines have that may affect some positions which occured in previous
games, already.)
