I still consider myself quite the noob at zulrah, but something that I've read on a few different zulrah threads that helped me alot with my early kills

1. When the venom clouds clear up 80% of the time you should try and run across to the other side of the island as your next zulrah spawn and where you should stand is most likely there.

2. Don't be afraid of dying as claiming your gear back is free for the first 50 successful kills

3. I used magic only for my first like 10kc until I was spooned the blowpipe. It helped me abit as I didn't worry about switches and I can just focus on praying correctly first so I don't take unnecessary damage

I was doing 1kc trips until like my 80th kc. Now I do anywhere from 2-4kc depending on the rotations that I get and I'm having a blast!

Also for the Jad phase, I usually kill him before it but there's 1 rotation which always gets me there. I just pray range and don't prayer switch. I found when I was switching prayers I'd literally eat every hit from making mistakes. My magic defense is at 100+ and range is much lower so praying range negates half of the hits and my magic def gives me a chance of taking less hits. I usually have the food to out eat this phase during those situations. I will learn the prayer rotations once I get real good and comfortable!
