If you are using the Adafruit_SSD1306 library, and do not care about displaying the Adafruit logo splash screen, add the following line to the Adafruit_SSD1306.h file in the library, it will free up a bit over 1KB of program memory.
#define SSD1306_NO_SPLASHIf you are not going to be using EEPROM for anything else, I'm far from convinced that you will be saving any memory by storing this data in EEPROM, since the code for accessing the EEPROM is going to take up some amount of program memory. Are you intending to have the code modify the data in EEPROM, or is it constant?
