Okay, I am going to attempt to answer your questions, but I will do so in an order that I think is logical - so it might not fit your questions exactly - but I will give short answers to your questions at the end.

1. Utah has 76-10-500 Uniform law which states:
So, no, the DWR cannot enact or enforce any ordinance pertaining to firearms that is not already in the law.
2. There's no real reason to debate section 76-10-502 in the code, we should know when a weapon is deemed loaded.
3. Utah code 76-10-504. Carrying concealed dangerous weapon -- Penalties states:
According to subsection 4, you are allowed to carry your defense weapon while hunting as long as you do not use it to take wildlife. As open carry is still being defined and written into existing law, this is an area of confusion for those who do not understand the law, but are supposed to enforce it. As you are legally able to open carry elsewhere in the state (except federal facilities, etc), according to the Uniform Law, open carry while hunting cannot be prohibited - just don't unholster it unless your life is in danger.
4. Utah code 76-10-505. Carrying loaded firearm in vehicle or on street has an important statement in subsection 1:
You have been "authorized by law" as a CFP holder to carry in your vehicle and on a public street, etc. Section 505 allows you to conceal or openly carry where you choose (except prohibited areas previously mentioned). Public land and parks (where you hunt) are not allowed to regulate your methods beyond the laws the legislature has set forth.

To answer your questions:
No. Having a permit only extends your rights in the eyes of the law, it never restricts them. Public agencies cannot enforce or enact laws that are contradictory to state code.
No. You have the right to have loaded firearms in your vehicle if you have a permit. It doesn't matter what you are doing or what you are wearing. The permit allows you to have loaded firearms in your vehicle, even if you do not use those firearms as your primary self-defense weapons.
No. As stated before, you are perfectly within your rights to carry loaded firearms on your person or in your vehicle as long as you are not in prohibited areas. It doesn't matter if you are on a nature hike, a scenic drive or the hunt - the DWR is not able to restrict your rights any further than state code has done already.
