couple questions.

With my wraith having stock gearing 20/80. It has mickey Thompson Baja claws on it and they are weighted. They weigh~3.5oz each. Should I change the gearing in the axles to help turn them? I've seen gears that are like 13/36 but idk what stock is and idk how far to gear them down. I don't want under/over visa versa. Just same front and back.
I'll be using it in one of Peoria arizonas big drainage canals the spot I go to is dry for the most part but when it rains the sand and dirt and rocks down there start to look fun. I'll be ballooning my cc mamba max pro and lipo. I'll get some marine grease for the trans and axles too. Should the connecters be covered too so water doesn't get to them? Anything else need to be protected from water.?
I'm not going to full drown it. Just get her wet and throw some water around.

Change the spur and pinion ratio period. Its gears way to tall out of the box and should be changed immediately before driving. That will help tremendously turning the bigger tires. All I run gear wise in the axles is stock (37/13) hd gears and it works fine. But changing the spur and pinion is a must...

stock gears are 38/13

Definitely change the gearing, maybe also conside moving to 32p gears while you're at it.
