Hello there,
i'm a new GM and would prefer to run the pre-made module first, before doing my own plots, what would be the "best" order in which to play the modules ?

severe tangle
I recommend starting with Operation Solstice Rain, which then leads into Operation Winter Scar.
That will occupy you for the better part of a year, so you don't need to worry about what's next for a while.

I agree with the above, there is an angle you could exploit going from winter scar to Dustgrave and Sirens Song but it's tenuous at best and would require you to scale up both modules.
Mild spoilers, nothing significant but spoilers none the less
||Tenuous link is both Dustgrave and Siren's Song have a focus on NHPs and you could have the NHP that goes missing at the start of Dustgrave be Rio from the ship in Solstice rain, then as people who are familiar with dealing with issues around NHPs you get sent to do the Sirens Song mission after.||
