Worming and inoculations requirements are also dependent on your location. Most people also use more than one type of wormer because not all parasites will be killed by each type of wormer. Shearing is done in the early Spring in the South, usually later in Spring in the North. This is a must to prevent heat stress. You don't want to shear too close, as you want to avoid sunburn.
Some people use hand shears, others use electric clippers, others use a combo of both.
That's something to ask about at farms you visit, especially if you don't think you want to attempt the shearing by yourself at first. I've hired a professional shearer to come and shear my llamas, plus I've invited the new owners of llamas I've sold to bring their llamas to be shorn every Spring. We're trying to learn the art, but llamas sure look prettier when the pros do them. You'll need to keep toenails trimmed, but how often will depend upon your terrain and the individual llama. This is no problem with a properly desensitized llama that's been taught to lift their feet calmly.
