Concerning the questions, there is a 10% chance of finding a Dome Fossil and a 10% chance of finding a Helix Fossil in the smashable rocks in the Bay Cave. Since they're both a key item, you can only get one of them at a time. So if you have one Dome Fossil, you can't get another Dome Fossil until you bring the first one back to life. Having a Dome Fossil doesn't have any effect on your chances of getting a Helix Fossil. To clarify, this is not a bug.
After beating Drake there is an event on Shamouti Island. After finishing that event, Tracey can be found in Pallet Town.
Prima is in Mandarin South, she's available to battle whenever you want. Although I don't recommend battling her the first time you come by.
