hill descent control f250

Should have my new f250 powerstroke diesel by the middle of next week. Bought this truck sight unseen. Just some questions about towing on grades.
My former truck was 2009 duramax/allison. Loved it.
The following features are what I loved about the duramax when pulling my fifth wheel and am wondering if the powerstoke has the same features?
1. in tow haul mode the engine would kind of gear down by itself when coming to a stop
2. a button on the shift lever allowed me to shift up or down at will
3. in cruise control, the engine and transmission would hold the truck at the set speed on downhill grades

This truck also comes with a feature called "hill descent control" Is this used only at slow speeds in the back country or this also of use on the interstate with significant grades?

Last question. It also comes with electronic locking axle. Does this lock out the rear differential? How do you activate it? Is this useful only when stuck in mud and snow or is it for driving on slippery roads as well.
