There are a bunch of posts on this topic, and you'll probably get more answers than people responding...but honestly after you play for a while it really stops mattering. Dwarves rarely last you throughout the game, and once you're comfortable with the early game it really doesn't matter how you start.
As a beginning player, just do whatever you need to survive...but the reality is that no matter what you start with, you're going to die if you don't know how to keep going.
For example, a little food and no alochol comined with skilled herbalist and brewer is a perfectly good way to start. But if you try it as a new player you're just going to die senselessly.
During the moderately early part of my Dwarf Fortress career...right as I was starting to consistently be able to survive past winter, lots of food, and everything else invested in skills worked ratehr well for me. But again, initial investment doesn't make much difference once you know how to play. Your real priorities should be learning how to irrigate your farms, how to brew alcohol, and turn it into meals. Once you can consitenly do those things, you should be able to make it past winter more or less regardless of how you start.
So...to answer the question, personally I invest points in skills of convenience. Carpentry. Masonry. Detailing. A pair of miners to speed up digging past the chasm, and then usually a pair of farmers to simply farming later on. I don't usually take much gear. Never any animals. Usually no alcohol. I find that it's unneccesary for the first year of gameplay. And I usually play on heavily forested map so I don't need the barrels.
