Augmetics - when you acquire them, they are may not be "standard kit," but you're not going to lose them. I would say its worth 2 points, as its an excellent means of self improvement.
Chameleoline - The cloaks are standard kit, and if the regiment makes heavy use of snipers, or is otherwise stealthy/shooty, its worth 3 points
Combat Drugs - Slightly weaker, but useful if a medic is present, or fighting is particularly close quarters. The actual kit modification is a bit odd (not sure if you can restock up to 5 doses, and getting more is the requisition test, or if restocking itself takes a requisition). Debateably worth 2 points, good for those who don't want to mess with augmetics.
Demolitions - General bonus to getting explosives. Great for armoured companies who want to make use of the specialty ammo. Worth 3 points if you have a regiment type or players that use explosives.
Scavengers - Free logistics bonus to anything, with an annoying penalty (but aliviated by a crooked commissar who understands the necessity of taking what you find; its about winning wars, exitus acta probat). Generally worth 3 points, as +10 logistics to all tests overrides what demolitions and augmetics do (although don't ask how you scavenge for augmetics).
Warrior Weapons - Probably the worst, I don't want to defend it. Parry is about the only good thing, as its semi difficult for many to imrpove. The availability really should be improved by a step (players should be able to get their hands on chainswords with the doctrine). Only worth 3 points if the whole party is filled with masochists who want to find themselves in melee combat.
Well-Provisioned - More ammo is always good, but the real kicker is in the fine print. 2 more weeks worth of rations. Doubled rations. And +10 for vehicle maintainence checks that are logistics based. Rations = trade currency with other regiments. Then just get more of your own when it comes time to restock on standard kit. Also, the food helps to make sure you're not having to cook your boots for something to eat when the winter sets in and you're cut off from supply lines. If I had 3 points available after all else and mechanised infantry, I'd take it
I would certainly say Augmetics and Chameleoline are worth the points.
Scavengers and Well-Provisioned are possibly nice, but take some work to get the hang of why its useful. Well-provisioned is also very much dependent upon the regiment type (you need a vehicle, you need grenades, you need a main weapon that you're actually going to use the ammo from).
Combat Drugs and Demolitions I would say take a specialised campaign/level of group think. Either Armoured company/heavy gunner w/ mortar/missile launcher, OR a crazed close combat squad that shoot up on frenzon before charging.
And warrior weapons is just terribad.
