What can i do if my uncle died from pancreatic cancer. does this mean my dad has a good chance of getting it?

Probably not: It depends on the type of pancreatic cancer. The most common type (not the one steve jobs had) has a weak genetic link. A person with a first degree relative with pancreas cancer has only a modestly elevated risk of getting pancreas cancer.

Unlikely: If your uncle is the only relation who has had pancreatic cancer, you are unlikely to be at a dramatically increased risk. Make sure to get a complete family history of all your other relatives to make sure there are not any more pressing abnormalities.
