As a new diver, I would spend the money in the following order.
Computer
Wetsuit
Regulator
BCD
Tanks
Given your location, you may or may not need to get a wetsuit right away, unless you plan on spring dives or diving during the winter.
I'd start off with a computer. Doesn't need to be anything fancy, but if possible look for one with some sort of logging interface. Bluetooth is preferred, but cable will do for now. Factor in the cost of the computer if you need one, as that may make up the difference between a cabled and bluetooth version. When I first started diving, I didn't have a computer. My dive logging habits weren't the best, and I've lost some paper logs through the years. With my first computer, it had logging ability, but I never had the cable. So, there is a significant gap in my current log. Computer will help you real-time on a dive. It shouldn't happen, but if you were to overstay your NDL, the computer can get you to the surface safely. Look for one with at least 2 buttons. The single button models can be hard to cycle through the menus.
For a wetsuit, fit is important. Also important to know your cold tolerance. I have a couple in varying thickness, but really only use my thin one most of the time. IIRC, it's 2mm, and I've used it in the Gulf down to lower 60's (with a 1mm rashguard).
For regulators, any regulator will work. A balanced regulator will work for now and later, while a cheap unbalanced reg may not be ideal as your diving gets deeper. Steer clear of the bottom of the line, and there is no need for top of the line titanium versions.
For BCDs, rent for a while. Try to rent different types (jacket, back inflate, backplate) if possible to get a better idea for what you like best.
The bulk of your $1500 will be spent on the regulator and BCD.
I'd absolutely recommend waiting for now and/or check Craigslist, Ebay, Facebook, etc. for the used market. Lots of students or newly certified divers buy a bunch of gear then never use it again. If you do end up buying used, don't use it until you've had your dive shop service (especially regulators) it, so factor that into your cost estimates.
