A future version of Sleep Aid will include better internals for quantifying battery drain during sleep, and at that point we'll be able to say for sure which combination of settings will have the biggest impact on battery life for your Mac.
In the meantime, these settings should enable the least energy usage during sleep and should improve battery life available for actual work.
If at any time you become specious that these settings are no optimal for your Mac, please use the "Restore Defaults" button in the "Sleep Settings" window to revert these back to Apple's preferred settings.
Also note: That disabling Wifi, may prevent "Find My Mac" from being able to locate your Mac if it becomes lost or stolen. Disabling "Bluetooth" during sleep, will prevent Bluetooth keyboards and mice from waking the Mac.
