The below'll be a bit of micro-optimizing of what you have. It might give you some ideas and advices to work with. And I'd not recommend going as 'raw' as below anywhere you're expecting trouble
Iron Anvil
Never go anywhere without one! Even if you're prepared, you'll always need an anvil. Just in case, y'know!
Also you want a rock to bring along, they're only 3 points and can be made into blocks for 4x more material. Smelters, wood burner and forge need fire-proof material, which I don't see elsewhere on list except for gypsum and I'd not recommend taking that for reason below.
2 Copper Picks
Bring one copper ore and one of either kinds of coal ( if it's avaliable, 5 pieces of wood if not to smith all the bars ). Bronze are slightly more efficient with coal but only if you need a lot of tools.
EDIT: Forget to mention that each ore gives 4 bars of metal, thusly the 5 pieces mention, one to smelt it, and four to forge it.
Native copper or Malachite's 6 each and either kinds of coal are 3 points, lignite will provide 5 cokes or bitumitious giving 9. If neither's around, 5 woods totaling 15 points will do the job. So around 9 to 21 points compared to one copper pick worth 44 points
3 leather quivers
2 cave spider silk bags
Save around 15 points if you brings leather for quiver, and another 10 points bringing leather to make bags instead. 5 pieces of leather's 25 embark points, compared to 50 points for above. I'd advise taking more leather as needed.
one training axe
Bring one piece of wood worth 3 points over bringing training axe worth 17 points. Or alternately use leftover copper bar from pick making and have it virtually free as byproduct.
15 plumphelmet spawns
9 dwarven wine
6 plump helmets
I would take around 10 plump helmet for all those. one plump helmet makes 5 dwarven wine and one seed. One seed and 5 units of booze's worth around 11 points with one plump helmet worth 4. With 5 stack being norm, 20 points of plump helmet can give 25 booze and 5 seeds, norminally costing 55 points. Throw in wood and it's still decent.
*Other seeds*
Keep the other non-plump helmet seeds, I always takes at least 10 of them more out of habit!
*Other alcohols*
My habit's to take as much plump helmet as I thinks will last me a while, and plenty of wood. It protects me from cold weather issues and is slightly better in points spent in my eye. Variety does helps dwarven mood, though!
5 gypsum
Not really worth it, since it'll need bags. Bring wood logs to make splints on-site and save some bags, it cost the same either way but wood splints don't need bags.
5 cave spider silk threads
3 cave spider silk cloths
1 cave spider silk rope
Don't buy cloths and ropes, buy more threads to make them. Well, this one might be a bit distracting since it's only one point more to get cloth and four point to get rope over threads.
*Various milk and meat*
Trying to get more barrels on the cheap? It'll work if you only buy one of each specie that's worth 2 points. I prefer to buy wood instead even with slight more expense.
5 tower-cap logs
That's very little wood by my standard, but if you're expecting to be able to chop a lot trees down then that's okay! You'll need one to make into charcoal to start processing coal if you're following the ore route.
*Various animals*
I don't recommend buying any baby or trained creatures, you can either train them on-site or buy fully grown creature to butcher/breed. Cavy's too small to be butcherable, unless you intend to use them as pet or watch-critter? Can get away with not buying leather and meat if you buy extra critters. I'd estimate that peafowl, chicken or turkey should be able to give one leather each and some meat and bone. I personally prefer peafowl!
EDIT: Forget to mention another reason to not buy baby creatures, they're as expensive as fully grown one.
