Just started the manhwa

I just started the manhwa after binging the anime after telling myself every time "I'm gonna read that later." There's a bit of regret that I did not pick up this peak sooner than I should've, but I'm just now more excited that I get to hyperfixate myself on a new, shiny, PEAK literature (again?) after finishing the JJK manga (well, if you know, you know).

I'm just curious now that I figured there's a novel and another SL Ragnarok: in which order should I read them and does it matter? Also, what else SL content is there that I should, I don't know, prepare myself or make sure to try/check out? I'm definitely continuing now on this chapter (pic provided) onwards and I know I still got a long way to go, but hey, have I told you that this is PEAK?!
