So,
1) There is no criteria for setting a seed. People can use any number, and, as you saw, it helps to get reproducible results when random numbers are involved.
2) yes, rifhdreg does the same and more compared to rifreg. Now, if that is enough will depend on what is it you are trying to apply the estimator.
