The fact that they can clinch these things tonight means that these will all happen by the end of the week at the latest. But it's still fun.
1. With a win of any kind, the Pens will clinch the Atlantic Division title. First tiebreaker is ROW, and the Pens already have that sealed up
2. With a win of any kind, the Pens also clinch at least the #2 seed, meaning they will have home-ice through the first two rounds of the playoffs. The Caps can still catch the Pens' ROW, but the Pens beat them on the next tiebreaker, which is head-to-head points.
3. A Caps regulation loss on its own tonight would also give the Atlantic Division winner at least the #2 seed.
Again, this all has a 99.9999% chance of happening soon if not tonight, so whatever. And don't fact-check these stats because they might be wrong.
