What episode does the 4th great ninja war end/Climax to the end begin? Also what important fillers are mixed up in the episodes?

I'm asking this because I don't want to watch 5 minutes of battle per 20 minute episode. I'd very much like to just skip to the final battle. I've already seen the two episodes with the founders of the villages, and was wondering if there was any other important episodes like it mixed in? I'm actually near the middle of it, and I've already witnessed that one scene within where that one person is defeated. (I'm trying not to give away any spoilers to people who are just starting Naruto. I don't actually mean defeated. But the other word starts with a D too.)

Anyway, I'd be extremely grateful if anyone could help me out. I really want to continue the rest of the storyline already.
