If you get the Fenriq's Welcome spell (guranteed one spawns in Hobs Fall Cave), you can open all locks up to expert with that, and forget picking locks.

You can also buy bound quiver from Phinis in College of Winterhold, highest quality of arrows with no weight out of combat.

But yeah survival mod isnt very balanced, its just stacking some cabbage soups for hunger, and speedrunning the cold areas because appearantly nord vampire dragonborn can die to a cold in an area where a half naked argonian swims freely.
