Squats, power cleans, hang cleans, front squat, leg press, snatches, etc?

I've never seriously lifted weights and this year was my first year wrestling, while I progressed quickly with my technique, I realized that sometimes strength can be a huge variable in a match. I do a lot of body weigh exercises - push ups, pull ups, sit ups, pistol squats, etc. These are good, but I feel like I'm not getting the most out of what I could be.

What lifts should I do to become the strongest I possibly can?
