I feel and I am sure most will agree that you are planning way too far in advance. Of course you can have goals and dreams, but you should take your diving one step at a time. You really don't have much of a choice anyway, basically after your 1st scuba class the next step will be the Advanced class, then after that the next step is Rescue Diver, and then things start to open up depending on your intended direction. Most of the others you talked about; deep, wreck, night, navigation, etc. are all electives. Basically they are just a small intro into the subject, but not full training in any way. The nitrox training is somewhere in between, as you don't need it to progress from basic scuba to advanced, or to rescue or even DM, but you most likely will want to take it at some point.

Bottom line, by the time you actually have a choice in classes (besides electives) you will already have enough scuba knowledge to make your own educated decision.

As far as the electives, take whatever you are interested in, and remember they are only a small introduction to the subject!
