First visit to Icmeler... Help!

I'm going to Icmeler with my family in a month but I'm afraid I don't know much about it. My mum wants to go to Ephesus, would that be possible as a day trip? How far away is it? How much would the journey cost? When would be the latest we could visit Ephesus? How much would it cost to visit? My brother wants to see the tombs in the rocks, I'm sorry I don't know where that is though, is it Dalyan? How far away from Icmeler is that? How much would that cost? Any help or information would be great! Any other places you'd recommend visiting?
