First off, I feel slow should be worth 2 extra points; It drops standard move action by 5ft, a charge or double move by 10ft, and running by 20-25ft.
Steady should be an ability costing about 1 point; it mitigates the problem of being slow but the benefits aren't really worth much.
In the same stead, anything that grants fast movement (10ft to base speed) should cost at least 2 points. Fleet, a feat, only grants 5ft to the base speed.
While xenophobic may be worth a flaw simply of the inability to speak common or undercommon though that is easily negated through a single skill point in linguistics, the difference between standard and linguist is extremely minor. It's very rare that a player will be able to use even 1 of the exclusive languages which can be simply gotten from putting a rank in linguistics. Hence I feel that anything to do with languages is setting specific and up to GM discretion.
Some abilities are so weak yet specific that making them cost any points is silly. One such example is Greed which does grants a +2 to a rarely used skill with specific items that rarely if ever show up. Also Hooved, as written should not cost anything (and is actually a penalty with anything less than 4 legs) as being hooved does not grant natural attacks and limits the items you can wear.
A GM should be weary about adding too many of these 'free' abilities, but other than that, it should be fine to not make them cost anything.
They should cost 3 points. Skilled should cost 3 pts, not 4; Adaptability, Hardy, and Gnome Magic should cost 3 pts, not 1. They're all powerful abilities.
Bonus Feat, I'm okay with it being 4 points for the following reasons: it's customizable, meaning a player can optimize it for any build; it can be used as part of a feat chain.
Should cost only 1 point. +2 to a specific ability is nice, yes, but it's set in stone and doesn't provide ranks or increase with ranks.
And with that reasoning I re-measured out how the races would be balanced:
