Silverblade, if you're aiming at "detail enhancing", I would say that texture AA will probably do the opposite. That's what's written in the manual and it's my experience too. Here's what the manual says about texture AA:
"While the results produced using some amount of filtering are generally smoother, you may
occasionally find that your images are not as crisp as you would like them to be."

Personally, I only use texture AA when I see Moire patterns.

Another important thing is the quality threshold in object AA. I would say your setting is ok for characters and nomal objects but it's too low for plants in the distance, like grass or similar. It's also too low for some kinds of spectral clouds (grain is likely to appear). Whenever I have clouds or plants, I normally use quality very close to 100% (exact amount depending on specific types of plants and clouds). If I have just a normal interior setting, no plants, no clouds, 50% is normally enough.
If you have quality AA at 100% or close, it's pointless to have min subrays very high because the render engine itself will evaluate what's necessary. I normally have it with 8 or so.

The "compute physically accurate caustics" will effectively slow render tremendously and if you just have an ocean in the distance, for example, it will not be noticeable at all. IMO, this setting should be set only when whatever's behind the water level is clearly visible to the viewer. Or if you have glass stuff in close-ups.
