I bring a 20 booze of 3 different kinds, 20 bituminous coal, 20 wood, 20 copper bars, 10 magma-safe stone, 3 cats, 3 dogs, an anvil, 3 buckets, 15 plump helmets, fish, meat, 6 of each kind of seed, and give each dwarf 1 point in ambushing. I believe I gave one of them even more ambushing skill. The idea behind that was to get free crossbows and crossbow skill, but the whole crossbow-using thing turned out to be broken. I also have yet to actually plant any of the seeds I brought, as all of my farms are outdoors.
The first two things I do are:
1. Build a wood furnace, smelter, metalsmith's forge, and carpenter's workshop. Burn 1 wood. Begin building beds from the wood we brought. Make coke from all the coal, then make copper axes and picks from the copper bars.
2. At the same time, make a couple food stockpiles, and begin plant harvesting the outdoors shrubs, and brewing them. Then set up outdoors farms with the seeds. At some point find something (such as animals) to cook. You get a ridiculous amount of food from butchering animals. I don't cook booze, and if you try to cook nothing but booze, the dwarves don't seem to know how to make soup without spilling it all on the floor. Dwarves can also eat fruit raw (and plump helmets). Fish all the fish and turtles up, and DO NOT USE THE SHELLS FOR CRAFTING. I did, because they were filling up my refuse stockpile, and I didn't realize I would never again find any more turtles.
