As someone who generally recognizes the value of education and who is clearly in the minority opinion here, I would say don't bother with most of those classes. Take the rescue class and dive the things you want to dive. The rest will come with time. Take that back, take the rescue class and the nitrox course if you want to breath voodoo gasses and of course wreck penetration/cave courses if you're into those things but all the different specialties are unnecessary. As long as you're doing NDL diving, you already know the major points of what you need to know. Experience, especially with mentors, will fill in the rest and give you a much better/broader diving resume than taking a bunch of classes will.
Yes there is value in the classes, if taught by a motivated instructor, but most of the information can be (and likely already has been from what I know of your posting habits) gained here on scubaboard. You likely already know the symptoms of narcosis and other pitfalls associated with deep diving. Diving 60 feet in a cold low-viz quarry, I would argue will help you with deeper clear-water dives, though, since it will increase your comfort level overall thus giving you a better SAC and more bottom time, etc etc.
I guess my point is it ends when you decide you'd rather dive than take classes. Education doesn't have to stop just because formal instruction stops.
