I am Lalafell, so I can only really answer number 1, though I really shouldn't as it is something we generally prefer not to discuss.
Miqo'te do not eat Lalafell, though their primitive ancestors might have liked too. When Lalafell first encountered the Miqo'te they where only a small semblance of what you know (and often love) today. There where both Male and Female Miqo'te and both sexes where extremely primitive and violent with limited ability to communicate among them selves, let alone with us Lalafell. They only used the most primitive of tools, mostly crude spears and blunt clubs.
Unfortunately, the males where extremely violent and territorial to other races. At first, it caused us little problem as our mages and advanced knowledge of the sciences such as alchemy and metallurgy where all we really needed to protect ourselves from these primitives. The true problem, as you alluded to, is their food supply. As a hunter/gather tribal species, they had no real ability at creating a sustainable food source for themselves, nor the ability to learn the necessary skills. Eventually we realized, a little too late, that their fast reproductive rates, females at the time where observed to have up to 8 offspring in a liter, and fierce physical abilities, they would eventually over run us despite our advanced skills. This became more and more apparent as their food sources dwindled. They also had a large impact on our own ability to maintain our own crops and farms as they fiercely began raiding for food.
Around this time, I wont go into detail on to how this particular "research" began, a Lalafell scientist discovered that Lalafell and the Miqo'te where genetically compatible mates. Further more, female offspring of a Male Lalafell and Female Miqo'te mating where born with vastly superior intellect and a much more "tame" disposition, though they could still be somewhat fierce compared to Lalafell or Hyrul females. These results where very surprising, but unfortunately male Miqo'te/Lalafell offspring did not receive what ever genetic gift the new breed of female Miqo'te where being gifted with, despite our courageous females best efforts to mate with these beast. Testing indicated it would be highly unlikely any of the "new breed" of female Miqo'te would ever be able to produce a "tame" male Miqo'te and we did not have the time needed to wait until they matured to adulthood for further testing.
Not long after the first confirmations of the cross-breeding research results a Council of Male Lalafell voted to enforce a population control measure on the primitive tribes of Miqo'te through the introduction of a biological agent our best government Alchemist determined would drastically reduce the Miqo'te reproductive rate by limiting them to one offspring per reproductive cycle. Unfortunately... there was a unforeseen outcome after this agent spread through the Miqo'te population, which now included some dozens of "new breed" Miqo'te... After the introduction of the population control measures, all Miqo'te offspring where born female.
Eventually the Male Migo'te went extinct and only females remained. Not long after the males died out, the last generation of primitive female Miqo'te also died out. Over time, the issue of the blunder with the population control would grow into one of the biggest Lalafell conspiracy theories and a source of shame to most of our race. In the modern day, this history is hardly ever discussed, even amongst ourselves, though not necessarily a secret either.
All Miqo'te today are the offspring of a Male Lalafell and to this day, all offspring are female. As a result, over the years it has become traditional for some Lalafell males to take a Miqo'te concubine or if he is particularly affluent; a harem of Miqo'te concubines, though we generally only marry other Lalafell. Concubines typically live independently and always raise their offspring without assistance from males, they insist on it, a carryover of their fierce and territorial maternal instincts to protect their young. When young Miqo'te come of age, they will seek out Male Lalafell suitors to bind them selves too, typically seeking out the largest dowry in exchange for a three to five year commitment.
