My usual embark consists of:
One Dwarf with five levels of Planter and one level of Weaponsmith.
One Dwarf with three levels of Brewer, three levels of Cook and one level of Armorsmith.
One Dwarf with two levels of Diagnostician, one level of Mechanic, plus Management and Social skills (Expedition Leader)
Four boneheads (no skills).
Explanation:
Skills like Miner, Mason, Plant Gatherer, Lumberjack and Carpenter train so quickly that it's really a waste of points to buy those skills. Instead, I give my all-important Planter and Brewer/Cook lots of levels in their base skills, plus one level each in a valuable MOODABLE skill (planter, brewer and cook are NOT moodable) so that when they get a Strange Mood it will give me a Legendary Weaponsmith or Legendary Armorsmith instead of a Legendary Bonecarver (the default for Dwarves that have no moodable skill).
For embark items:
Take ONE of each $2 meat (only one type per source-animal: if you take sheep eyeballs, then skip sheep intestines) since the meat from each different source-animal gets a separate FREE barrel. One piece of meat from each of twenty different animals gives you twenty FREE barrels.
Twenty-one rations of each of the four drink types. Sixteen (or twenty-five) Plump Helmet Seeds, along with nine Sweet Pod seeds and six of each of the other seeds. Twenty-one (or twenty-eight) Plump Helmets.
I like to embark on Aquifers, so I take several stones along for making mechanisms (in case I need them before I can get through the Aquifer and reach rock).
Three Picks and an Axe (unless you want to just bring the stuff you will need to make them instead... ores, charcoal, coal, fire-resistant stone, etc), since I like to train up my four no-skill boneheads as two Miners, one Miner/Mason and one Lumberjack/Carpenter. Other players will tell you that those two jobs (Lumberjack and Carpenter) should be given to different Dwarves... but you'll be getting lots of totally useless immigrants (Dog Barbers, Bee Psychiatrists, Turtle Milkers, etc) that you can re-purpose early in the game to split those skills.
One Anvil. No Wheelbarrow (you can just make a few). Thread (cave spider thread or yarn are cheapest). Three Gypsum Powder.
If I have points left over, I usually bring wood, stone, ores and coal in order to get a quick start.
