I'd suggest upgrading your wood shield before you find any copper/tin/able to make bronze for better equipment & armour. You can also make a torch, grey dwarves won't come near you, they hate fire. Use your antler pick to gather tin & copper, find surtling cores in the burial chambers & should unlock smelter & kiln, (you need 5 cores for smelter or kiln, so recommend finding 10, to build both) you need these to process tin & copper to unlock your forge, and craft bronze, etc. Also try to do your mining during the day to avoid being overrun by dwarves at night, but look out for trolls, too. Also stock up on a fair bit of food before you venture out, and get the rested buff as often as possible before you do.
