yes you are correct a,b are integers not element of group.

Are you saying that in IBE, PKG is not necessary.

comment In a group, is it hard to calculate the base $g$ given $g^a$ and $a$?
is it mean that in cyclic group it can be calculated by finding inverse of a, but in general like RSA encryption it is not true.

correct. but in modulo arithmetic is it correct?
