When do side focus scopes come into use?  Larger magnifications?  Long range shooting?

Side focus has the same function as objective focus, that is to focus out any parallax error.
Generally, the larger the magnification, the more parallax error can effect your aiming and accuracy.
First and foremost is what type of shooting you will be doing. Where quick shooting is required, such as some types of hunting, SF is impractical due to time constraints.
The general rule of thumb seems to be that for 10X and higher magnification SF can be beneficial.
If you are going above 10X and require a high level of accuracy, SF is the way to go.
A recent test I did shows that up to 200 yds and a 20X magnification SF is not a big issue. Going further out starts getting tricky without parallax error focused out.

on some models its more presise and on others its a complete gimick (your cheaper scopes) Some like SF better than OF, some don't.  Most tactical style scopes have a side focus for precision adjustment, some don't like that even on those scopes, I forget who it was that like the SS10x without the side focus better than with the side focus. They will chime in I am sure.

Use of the scope will be deer/elk hunting in Utah.  I picked up a Burris FFII 3x9x40 but am considering  a higher power scope.

I dont' think you need side focus for that.  its one more thing that can get snagged on branches .  Plus it is more likely to be turned by accident when storing, carrying your weapon than a AO.

What will be your longest shot or what is the longest shot within your abilities that you plan on shooting?

I agree with SVT, we wouldnt want you scope to get messed up or knocked off your zero while you were on a hunt.

Ditto. With the exception of hunting rifles (Varmint and Target rifles are a different story) specifically set up to be used out of a stationary type blind for shots over long clearings I would stay away from a A/O or S/F scope or for that matter any of the really high power scopes for your application. 9-12x on the top end will be more than enough for a rifle you are packing around the woods and mountains while still having plenty of magnification for a 3 or 4 hundred yard shot should you need it, especially on a target the size of an elk.  I took two Pronghorn this year with a 25-06 with a 3-9X40 FFII. The first at 308yds and the second at 325yds and that scope worked verry well.

SF does not effect the zero of the scope. The windage and elevation dials do that. SF merely brings the sight picture and reticule onto the same focus plane.
 
A hunter cannot pre-set his SF for the hunt. He first has to see the animal, determine the distance and then set the focus.

Classifying statement: I have never hunted in Utah.  That said, the Burris should serve you well.  9x should be enough magnification for appropriate shots on most big game animals at ethical killing distances.  The side focus on a pure hunting rifle will only be a hindrance to you, just one more thing to worry about.  Practice shooting at the distances you may shoot at will serve you better that the side focus scope or more magnification.

IMHO.

I totally agree, my point wasn't to say that it will mess up your scope settings it just would be more apt to be turned and catch on things than a AO

Correct SVT, the remark was to clear up a statement made by Spinner.

Yeah I just wanted to clear it up so it would be used again incorrectly.

Well, I bought a Nikon Team Primos 3x9x40 to compare the the FFII I also have.  Based on those in the know here, I decided not to go with a SF model.  Good news is, SWFA received my order yesterday and shipped it out.  Fast service.

The team primos will be a good scope as well. Either one will serve your purposes quite well.
