See the FAQ.

It should have two valves, one on the top, one on the bottom. Hopefully they have given you a shock pump. Attach the pump to the valves and pump them up both to the pressure that is recommended for your weight. Hopefully they gave you an instruction manual with a chart of weight or pressures, or there will be a sticker on your fork.

The weights on the fork are a terrible guide - might get you in the right ball park, more often way too firm unless you like running next to no sag.

Try 25% sag.

how do you deflate the fork without spraying oil everywhere

Why are you deflating it? There's no need to let all the air out.

But turn the bike upside down for a while before letting the air out of the negative chamber, so the suspension fluid can move away from the valve.

did that but the positive chamber still spits it everywhere
