basically at this point you should pick between having the vehicle compact Assault rifle or the submachine gun, everyone will have a pistol, and a shotgun, the marksmen have battle rifles with ranges even longer than the ARs. After you pick between the AR or the SMG pick 4 magazines of ammo for your shotgun, pistol, and primary (SMG or AR) take note that the SMG has 2 magazines, so you should actually take pick 5 mags worth of ammo for it.
after you select those, pick 4 grenades (all grenades will automatically have gecko tips, because I said so.)
The riggers will have most their gear stowed in lockers if they need it, and the VTOLs have survival gear aboard them, and a Nexi that you can copy programs over from, including the tacnet. I might recommend that you run your tacnet from that Nexus as it has higher stats than your commlinks, but that's up to your discretion.
I wouldn't think butcher would sweat, but hydration is still important. I've played a full cyborg character before and metabolic needs were still important, but things like sweating or contact vector drugs didn't come up, so I'd rule the same for you.
