New to 40K and Salamanders, advice?

I’m pretty new to Warhammer in general, with my first models being Skaventide.

I’ve gotten more and more into 40K, and the lore has led me to love Salamanders.

I’ve purchased Agrax Agatone, Vulkan He’Stan, a redemptor dreadnought and some upgrade sprus to start my Salamander army. I was then thinking of waiting for a Salamander combat patrol or set, but am I just dreaming?

I’ve also purchased some paints based on Warhammer shop employees advice, I think the greens were called Vulkan, Nocturn and Moot? But I’ve seen a lot of people use Warpstone?

I guess my questions are: 1) What models should I start with / how would you have got started with Salamanders if you could start all over again? 2) What colour schemes do you all use? 3) Any other general advice for a fledgling salamander?

Thanks in advance, Brothers 💚🔥
