Since my post meets ALL your challenges with all the maps you could ever wish for, I win all teh dorfipointses.
Farm management:
Create an advanced world with the base parameters except change embark points to 10,000.
Generate world.
Switch to dwarfhack and type startdwarf 10.
During equip stage, bring 100 of each seed type.
Max out 2 farmers in plant gathering and farming.
Max out 5 dwarfs for fighting. Equip them with steel.
Bring whatever else you want. Bring lots of pots and bags.
Embark.
Dig in.
Bring in your stuff.
Find dirt.
Build a 3x3 stockpile for each seed type. Seeds only, no barrels, no plants, no nothing except seeds.
Build 4 3x3 farm plots with nothing but plumps.
Build a stockpile for nothing but plumps.
Build a still and set to brew repeat.
Build a stockpile for booze only.
Find more soil, do the same thing for pig tails. Then do the same for sweet pods. Then do the same for Cave Wheat. Set all your dwarves except your squaddies to have farm labor enabled in addition to their normal labors.
You will never run out of food or booze, and within a year you will be getting happy thoughts from magnificint drinks or whatever it's called. Then get a cook going making easy meals. Then get a couple of rock crafters going for trading for meat and fish. Those 4 3x3 farms for plumps will provide you with an endless supply of plump helmets. It won't be long before you have literally thousands of them.
Then branch into above ground crops.
Then start a new fort and profit from your newfound knowledge, and name your firstborn Xcorps.
