This would fall into the realm of DM rule. Per Pathfinder RPG concepts all physical stat bonus items must go onto a belt and all mental items go onto a headband. This is for a couple of reasons. To limit the raw amount of ability bumping magic and to free up magic items slots for other items.
Additionally magic item pricing is set as a guide line only for most items. If you as a DM are OK with allowing the party to have these abilities spread out over many locations then your pricing looks fine. If you agree with the basic concept of limited slots then I would add a X2 or X3 multiplier to your final cost.
Enhancement bonuses to Ability scores should always be Even numbers.
So Amulet of Natural Armor +1/Str +2 would be the following:
Amulet of Natural Armor+1 (1 x 1 x 2000 gp) or 2000 GP
Amulet of Strength +2 (2 x 2 x 1000 gp) or 4000 GP
The Strength effect is more costly so it uses the base cost.
The natural armor effect is secondary so it pays a +50% surcharge.
The end cost would be 7000 GP.

This calculation is correct. But be sure to remember that it is the base price, so the price to create it is half.
While I have seen that 'unusual location'-penalty mentioned sometimes here, I haven't seen it anywhere in Pathfinder. If such exist (in terms of written rules), then I would love to see it ;-)
While statboosting item as a standard are either headbands or belts, adding any modifier besides the *2 for an additional ability, will make it cheaper to make a slotless item (And I for one, will do whatever it takes to avoid those frigging Ioun stones...).
I have two corrections to your calculations, and they're both good news.
First, there is no "specific location" penalty in Pathfinder.
Second, you don't have to pay the +50% stacking increase for the first ability, only the subsequent ones. "For items that take up a space on a character’s body, each additional power not only has no discount but instead has a 50% increase in price."
Amulet of Natural Armor & Strength
+1 Natural Armor = 2000
+1 Strength = 1000 +50% for stacking a second ability = 1500
Total price 3500
Cost to craft 1750

I don't quite follow what you are saying about slotless items being cheaper (because I believe they are more expensive), but you may be right about Pathfinder not having any written rules about different types of magic bonuses being linked to specific body slots, or improper body slots costing more.
I was able to find the rules for 3.5 (called Body Slot Affinities), but I couldn't find these rules anywhere in the Pathfinder Core Rulebook.
Here is the link to the 3.5 rules for it:
http://www.d20srd.org/srd/magicItems/creatingMagicItems.htm#bodySlotAffinit ies
In the original example of a Amulet of NA/Str, the strengt enhancement would be more expensive than a slotless one, if you add 50% extra cost for inapropriate location on top of the extra 50% from adding an additional ability (totaling a *2.25 modifier compared to the *2 of being slotless).
All thanks for the help and clarification!
First, there is no "specific location" penalty in Pathfinder.I think there are rules for this according to the PRD: Adding New Abilities It is all the way at the bottom and states: "If the item is one that occupies a specific place on a character's body, the cost of adding any additional ability to that item increases by 50%. For example, if a character adds the power to confer invisibility to her ring of protection +2, the cost of adding this ability is the same as for creating a ring of invisibility multiplied by 1.5."
Actually this is only referring to the fact that the additional ability has increased price, not whether it is placed in a certain slot or not.
If the item does not take up a slot, then the price is not multiplied by 1.5 (and might even be cheaper than the primary ability, in case of staves)

HaraldKlak is correct.
But if there isn't an extra "inappropriate body slot" cost (which seems to be the case), then the slotless item would be more expensive, right?
Something to keep in mind is that you're not really paying for items, you're paying for powers.
15g for the sword
300 for the masterwork modification
2000 for the +1
Most wondrous items are made out of base items that have negligible cost by the time you can afford the magic item, so it's not even counted.
A nice belt = free
+2 Strength = 4000
Total cost = 4000
A nice belt = free
+2 Strength = 4000
+2 Constitution = 4000 +50% = 6000
Total cost = 4000+6000 = 10000
A nice rock = free
+2 Strength = 4000 +100% = 8000
Total cost = 8000
You could use expanded augment rules.
A necklace of ogre teeth adding +2 strength could be attached to the amulet of natural armor. The necklace would be more appropriate to strength.
Under this system (which I might go into more detail in homebrew) a broach of shielding would be used as a cape clasp. Each item can have one augment item. Already in 3.5 you could use augment crystals in weapons or armor.

so how do you explain ion stones then?
