Ooohh wait... if your rear axle is still a stock/unupgraded Dana 35, I wouldn't even consider installing 36" tires. 33" is the biggest tire size I'd recommend for a stock Dana 35. If you upgrade the axle shafts to hardened alloy 30 spline shafts, you'll be good to go for 35" tires. 36" is pushing it for the front Dana 30 and for even an upgraded rear Dana 35. I wouldn't install a locker into a stock Dana 35 rear axle no matter what tire size was installed, its 27 spline carbon steel axle shafts just aren't strong enough for the locker or for 35" or bigger tires.
For the front, the type of locker depends on if you need to use 4x4 to get around during the winter. If you can manage in 2wd, then a front lunchbox locker like an Aussie, Lockright, or No-Slip is fine. If you must use 4x4 during the winter when driving on slick streets, I'd go for a selectable locker like an ARB Air Locker.
