I've been playing since the 2D days, and I've just gone back to my old 40d methods. Namely, stripping caravans of every single piece of metal, and using what I can.
I'm playing an ore-less fort (nothing in the ground except a few scattered gems in the caverns) and have survived for over eight years now, with a six-dwarf squad almost completely clad in steel. Gobbies don't have access to iron though, so in the first few years I'd gotten by fine with bronze and bismuth bronze (parent civ doesn't have access to iron, so no anvil on embark, but another dwarf civ I'm trading with has steel).
Right now I have loads of copper and bronze, all from smelting goblin equipment and metal crafts from the caravans. I have a distinct lack of gold or platinum, and the little silver I have goes to making warhammers. I have enough bronze that I can afford to waste it on bolts for practice, and my metalsmiths are busy studding everything with copper. My countess has to make do with brass furniture, though, as I don't have much in the way of precious metals, so I have to make up the difference by studding everything she owns with loads of gems (by micromanaging the jeweler's workshop). Still, with enough artifacts, she has her royal-quality rooms. Even the mayor and captain of the guard sleep on jewel-studded masterpiece beds.
I did lose my first few moody dwarves because I couldn't get rough gems until the caverns, but that's mostly due to me being too lazy to get glassmaking up and running early.
So. Not much different from one of my older 40d forts, except its harder to get invulnerable champions (early on I'd lose half the squad to ambushes from time to time, but now that the Countess has gotten Teacher skill up to Adept, they all have Competent Dodging or better now, and don't fall as easily to archer gobs).
It is fun, about as much fun as my best 40d forts. No gamebreaking bugs so far. (Wild birds making a beeline for your extra nest boxes is funny, and not really a show stopper, unless you consider easy food to be a gamebreaking bug). The quantum large clay pot storage is also useful when hauling roasts to the trade depot - one large pot holds 30-50 thousand dwarfbucks worth of food, which is usually enough to buy out the caravan. Easily avoidable by not making large pots.
I haven't fully exploited the other features (next fort will be a clay-brick aboveground village probably). And I am still playing on the very first worldgen I started after downloading .19 (second fort, though, first fort died to tantrum spiral after forgotten beast).
