In order to become a FT optometry professor, you really do need to do a residency of some kind. You won't be taken seriously as a FT faculty member in a program if you don't have a residency/fellowship competed.
As far as pay, expect from about 60K-80K as a junior faculty member, with the higher numbers coming from new private schools that have to create a draw. Experienced faculty (15 yrs+) can make around 100K, with the highest I'm aware of pulling in about 115K. Those are going to be people who publish frequently and have developed recognition in their disciplines. This does not include senior administrators (Assistant Deans, Deans, Presidents, etc) who can make hundreds of thousands of dollars for doing almost nothing beyond warming a desk chair in an admin building in some cases. If you think all of those tuition dollars are being wisely spent by your school, nope - a lot of it goes to paying padded salaries of the folks at the top of the food chain.
Obtaining fellowship status in the Academy (FAAO) is a good idea for anyone in academics, but it's not going to give you a huge salary boost. In academics, the number of letters after your name often takes precedence over skills and knowledge, but it does not often translate directly to much higher pay. That said, OD faculty who move up the ladder quickly usually have another advanced degree such as an MS, PhD, MBA, etc.
Regarding ABO Board Certification, that will likely get you absolutely zeeeeeero in terms of additional pay or clout within the OD community, at least as things stand now. As a matter of fact, I'd imagine a lot of ODs who took the exam are in the process of hiding it since they may have some egg on their face after the recent AOS lawsuit. If youre after something that will actually give you some street-cred, sit for the diplomate exam in your section of the academy (Peds and BV, Cornea and CL, Disease, Low Vision, etc). Diplomates in their respective sections are given more respect by those in their field, but dont expect to be paid more for having it.
