I'm certainly no expert on powerlifting, but if you're new to lifting in general I would concentrate on the big 4 lifts first, Bench, OHP, Squats, and Deads. You get those down correctly, you'll get stronger. Then once you have a good solid foundation, then start to target different non-standard excersises to improve strongman conditioning.
