Most .357 Magnum loads do not need mag primers, but some do. Your load book will give you an idea, although some just list mag primers with all loads. Speer # 13 & 14 only suggest using mag primers in .357 with HS-6, HS-7, H-110, W-296, & Lil' Gun. (hard to ignite and or very slow ball powders)

Your Remington 5 1/2 primers are mag primers, and will work just fine for your purposes.

I've heard the Remington 5-1/2 primers are no different than the 1-1/2 style except for the thickness of the primer cup. Equal bangage for both, in other words. But I've only heard this...

I wonder how they would do with full-house loads of H110 in the .357 magnum if there's no difference in ignition capability...???

I fully agree that Remington should do something to make their packaging of primers more understandable!

Unique does not need a mag primer, but will work fine with it. I would just stop .1 or .2 short of max since they used standard primers.

do you mean grains of powder or seating depth

Powder....Sorry. Crimp into the crimp groove. That will give you your O.A.L. for that bullet. That will vary some depending on how long you trim your brass, if you trim it.
