Depending on the plane's design, the winglets are a resource to decrease lift induced drag, they are not mandatory even between airliners (for instance MC-21 does not use them because the properties of the wing are good enough already without them, this may be caused by the natural flexing of the wing under load). B-2 does not use them or any other military bomber that I can think of, actually. So it is not a given that they are good or necessary for a given design.
while were speaking about range lets talk about the max range of weapons of these stealth bombers. Lets look at how the US envisioned how they will deploy the B-2 Spirit, and the weapons they have and their max range (none of which surpass even 1,000km in range). Now compare that with the VKS, who will NOT fly their bombers over advanced OPFOR territory/SAMs, like the US would. Kh-101 has a max range of 5,500km in the conventional variant, the Kh-102's with their thermonuclear tipped warhead would likely take less volumetric space on the cruise missile, leaving room for more propellant fuel. So the Kh-102 could reasonably have 6,000km range.
This is clear and has been discussed previously, in terms of turn-around times and therefore effectiveness in degrading the opponent's military capacities, a supersonic high capacity bomber like the Tu-160 is simply superior to an equivalent of the B-2. That indicates that the plane is not only going to provide strategic missile carrying capacities but also tactical ones, ISR, patrolling and who knows what more. Of course the idea to use the B-2 inside the Russian IADS with free-fall bombs is absurd.
PAK-DA with winglets, firing Kh-102's 1,000km off the coast, hitting strategic targets 5,000km in the interior.
Keep in mind that a good part or even the most of the missile's range is used to approach in unexpected directions, to avoid detection and AD sites, so it is not directly translated into range
Winglets will not be a problem as long as they are single solid composite part of the wing
Depends on the composite, carbon fiber is reflective to radar. And the problem problem with the winglet as said is the physical size and orientation of the surfaces, not only the material.
