I have sailed in this region in 98'' Pick up a copy of the Greek Waters Pilot by Rod Heikell. It was a great nav tool during my charter. It is now a weathered keepsake of my trip cause recorded my experiences in the book.
You might consider self provsioning, depending on where you are starting your trip. Most of the area markets will deliver right to the dock. The experience of the greek market and the savings are worth it.
I would be glad to go into greater detail but the chartering companies and the forementioned book are the best sources
