A key thing to keep in mind in these recent versions, is that with the material re-haul, bronze is a better material for armour and weaponry. However, bronze's value hasn't been edited to correct for this. Therefore it is relatively easy to set out with a full combat gear's set worth of bronze on embark, then use it to create a fast military dwarf. I usually embark with: One pickaxe, no battle axes, some 10 bronze bars (depending on how well you want to deck up a single dwarf, you can spend between 7 and 10 bronze bars, seeing as you can add mail shirts and caps) as well as a handful (5-8) copper bars. Of my starting 7, I always have 1 dwarf with proficient weaponsmith and armoursmith. This guy turns the bronze into combat gear and the copper into pickaxes and battle axes for woodcutting. I usually have my first dwarf doing individual combat drills by the time I get my first wave of migrants.
Always ensure that your first military dwarf has: positive level(s) in agility and no laziness trait. With laziness he will never do individual combat drills, which is what will make him an unstoppable monster. Without agility, he will never be able to chase down anything that tries to run for him, which will be disastrous if you want to hunt with him, or just for general usage. His agility will increase doing combat drills, but it is vital that he has it from the get-go.
I disagree with your 60-dwarf fortress layout. You have way too many military dwarves, and you have no way to sustain them. How are you providing armour and weapons for all of them with 1 smith and no furnace operators? Or are you simply not, and is that why you need so many of them? Never send out unarmoured, unarmed or unskilled dwarves to fight as they *will* die. In order to get a metal industry going (aiming for steel weapons and armour) I usually have 4 or 5 furnace operators. At all times 2 are making coke, the other 2 are switching between iron and pig iron, or iron and steel. If you don't have a sedimentary layer you can go with charcoal instead, but that's an even bigger work investment. You can always bee-line for magma early on (or simply never embark somewhere that isn't a volcano), but given how far there sometimes are to magma, I can't make this work.
You have a lot fewer miners and haulers than I have, and I guess this has much to do with the way my fortress is designed. I used to be all about efficiency, but things got so easy that I simply dumped it, and now I'm doing these overly extravagant hallways and open spaces. This requires a lot of miners, and subsequently a lot of haulers. My miners (or projectworkers, rather) double as relatively unskilled masons for whenever they need to build walls rather than tear them down (for instance, when I have to continue my pre-set spiral staircase through a cavern), and my haulers simply dump stone from around my fortress next to whichever project needs building.
