There isn't much mainly because sasquatches prefer keeping to themselves. A few go into the cities and, because of their ability to replicate any sound they've heard, get jobs as sound effect guys or other sorts of entertainers. IIRC, they have a high tendency to be magically active, and those that are are part of various shamanic traditions (i.e. they always get a mentor spirit/totem). Note that though their language enables them to understand each other just fine, there's something about them - vocal cords combined with the way their mind works - that makes them completely unable to learn to speak human languages. (Understand, yes, at least to an extent, but speak, no.) Communication with them is via a unique sign language - not ASL.
As for your bad guys, Humanis and Alamos are likely to ignore sasquatches; they're a complete different species, non-metahuman, and are unable to interbreed; they're considered sentient paranormals, not 'humans'. You'd be better off making your bad guys either a group of gangers who are harassing a small tribe that's living in some comparatively-forested and non-toxic area of one of the Barrens or one of the low-security normal districts, or a tribe whose area in the Salish-Sidhe has been discovered to have some valuable mineral on it, and a corporation is trying to harass them to leave the land so that they can buy and exploit it. Maybe the sasquatches can offer a little bit of the valuable mineral (gold, silver, whatever) as payment, since these guys aren't likely to be sporting mirrorshades, thousand-nuyen suits, commlinks, and credsticks ...
