If she had the 2-year residency requirement waived, then she should be eligible for the adjustment of status process.
So to answer your original questions:
QUESTION 1: What is what is the best (quickest) process for her to become a citizen?
ANSWER: There is no "best (quickest)" process for her to become a citizen. There is only one way. She needs to go through the marriage based Adjustment of Status process to become a permanent resident and get her green card
. She must be a green card holder/permanent resident for at least 3 years in order to be eligible to apply for naturalization
to US citizen.
QUESTION 2: Should we file a I130 and I485?
ANSWER: Yes. That is how you petition and she applies for the adjustment of status.
QUESTION 3: If she leaves the country, (travels home to see a sick relative) will she be able to enter the US again without going to the US embassy?
ANSWER: Yes,she could re-enter on the H1B if the employment is still valid. However this is not the way she should travel because it will lead to abandonment of the Adjustment application.
She should submit form I-131, Application for Travel Document, to seek Advanced Parole. Travel with this will allow he to leave the US and return while adjustment of status is pending, and her Adjustment application will not be abandoned.
