One book I have with a Totem pole carving is "Carving Totem Poles & Masks" by Alan & Gill Bridgewater. But the best would be to look some up first, as already said. I bought a small set of 6 carving tools from Axminster, only 31.78 , I was a bit dubious, because cheap tools aren't normally very good I found. But those are surprisingly good quality steel, very sharp and so far holding a good edge. (Henry Taylor Super Sharp Set) Very good for small work.
Please don't be tempted to buy the very cheap sets you can sometimes find in places like Aldi. They really are poor quality and will put you off carving. One of my clients at work bought himself a set of 12 the other day, they were useless as they came out of the box,would have needed a sledge hammer to push them through the wood and I spent ages giving them a better shape and sharpening them for him. And even then they don't hold their edges.
Better a few really good ones that you learn to use well rather than lots of cheap ones.
