That viewing order sounds confusing as shit just reading it. The only thing you need to know is the watch Razor after you finish season 3 really, and that is how Netflix and the DVD/Blu sets have it broken up as well.
As for where you are, you are in the golden time. Season 1 is this near perfect beast. But the middle of season 2 has this cluster of episodes that are the pinnacle of the series. Don't read the plot descriptions on Netflix, but just know that when you get to an episode called "Pegasus", you are in for a run of amazing episodes after that.
Having said that, even if I think the Pegasus arc is the best the show ever was, my personal favorite episodes are the four part beginning to season 3, ending with my favorite episode: Exodus Pt 2. It features some of the most badass and awesome moments of the whole series, and proves that you do NOT want to fuck with Adama when he is mad and had time to plan. Those that have watched the series know the moment I am referring to.
