Start by taking a Hunters' Education course.
Then, apply for your tags, next year (January for nonresidents, I believe).
Between now and the application period, you'll have plenty of time to study the hunt unit maps, to pick the particular unit you want to hunt in.
Somewhere in the process, your father will probably realize that the 'good spots' and 'secret spots' and all gone, turned private, or not so secret any more. Utah has changed a lot, in regards to hunting units, land management, and game management, over even the last 5 years (let alone the last 10 to 20 years).
If you're going to hunt with a rifle, you'll also have time to prepare yourself for one of the biggest jokes in the hunting world. Utah's idiotically-designed "Any Legal Weapon" (rifle) deer seasons see approximately 470,000 people heading into the mountains ...at the same time. And, all of those people have to push like hell for their deer, because they only get 3 to 5 days (depending on the unit). The environmental impact is MASSIVE and terrible, and also results in game animals being harassed so badly that up to 5% die of exhaustion during the short hunting season, in some of the more popular units.
I'm not trying to tell you that you shouldn't hunt in Utah. I'm just trying to point out that it's one of the worst states, as far as game management and planning. Utah is more interested in profit, than proper management and enjoyable hunts.
Case in point.... I lived in Utah until April of this year. But, since 1998, I didn't hunt anything but Elk in Utah. If I wanted to hunt deer, I went elsewhere (Idaho, Wyoming, Colorado, New Mexico, Arizona, Nevada, and Oregon are all better choices - even if you have never been there).
