Answer 1

Have you had, have, did you have, has Bob ever read, has, did he read, read.

Answer 2

1) -- Have you had ... (т.к. yet указывает на Pres. Perf.)
-- Yes, I have.
-- When did you have ... (when обычно требует точное время действия, а не его результат, следовательно Past Simple)
-- Has (т.к. 3е лицо) Bob ever read [red] this book? (т.к. Pres. Perf., значит используется третья форма глагола)
-- ... he has.
-- When (пояснение выше) did he read [ri:d] (т.к. после did идет первая форма) it?
-- ... read (т.к. last year указывает на время)
