Using no for nipping is appropriate, but always give her a substitute and praise her when she takes it so she understands the choice she has.
Exercise is so important in an active breed like a sheltie. I know it is hard when you don't have a fenced area and your pup has not yet completed her series of shots. Mental exercise can be used to help, although obviously it is not a total substitute for physical exercise. But to help occupy her mind you can try "seek" games...take really tiny pieces of cheese, meat or even Cheerios and hide them all around the house (under chairs, on window sills if your sills are low enough for her to reach), etc.,...then give her the seek or search command to go find and gobble up. You can also do this with her kibble if you are using kibble and instead of bowl feeding all the time, sometimes do her meal as a seek/search game. Anything that gives her something positive to focus on will help with the negative behaviors.
Eight weeks is an appropriate age for a pup to be taken from Mom and litter mates...so that shouldn't be a contributing factor here. I really think too little exercise and just being a puppy who is still learning what is acceptable and what is not are the probable culprits. I don't feel from what you have posted about her behavior that you are dealing with a nasty or aggressive pup at all. Keep interactions as upbeat as possible to cement a trusting bond with her. Lots of patience...puppy phase will pass!
