With your 5-speed, I wouldn't even consider 4.56. I ran 4.88 with 35" tires and considered it ideal when I had a 5-speed. If the 36" is a true 36" and is a heavy tire like a Swamper, you might even consider 5.13.
Caution that with tires bigger than 35," that your front Dana 44 is not really up to it where long-term survival is concerned unless it's kept on the street. With the exception of the ring & pinion gears, center pumpkin, and inner axle shaft, that axle is identical to a Dana 30 axle which is not up to anything larger than 35", at least for long-term use or for difficult trails which I'll assume you're doing if you need to run that big of a tire. The axle tubes, knuckles, u-joints, and ball joints are not really up to long-term support of a tire bigger than a 35". Not in my personal opinion that is.
