Neko-Chan: go with the spindle and roving! Alpaca is a bit slippery to learn on, I might go with regular sheep wool, but it is very easy to learn. And then you can try alpaca and then you can buy a fleece, and then you can buy an alpaca and a wool sheep..... (oh, and a loom. I don't have one. Yet. Except for a small 15 inch or so rigid heddle kiddie loom)
