The peoples faces and bodies are pretty uniform, and without much character, but this isn't that important early on. Usually everyone is in basically the same standing pose, so this is good to start out with. Catalogs- Sign up for a few at the website for the publisher.

It's better the more images from multiple angles of the same person, so trying searching for celebrities and tons of results will come in.Google image search- lots of dead and irrelevant links to wade through, but if you search for 'hand' you'll probably get a few usable hand images to model from.There's much in the way of cheap and free images on the internet and elsewhere: What you need is a good source of images of people- but I've gotten along without buying anything tailored to art. Drawing experience helps, but the nice thing about 3D is that simple shadowing is automatic- sculpture experience probably applies more directly. It's probably nice to have a good anatomy for artists reference book, actual art instruction background, or anything else specifically tailored for art. Teapots and other simple inanimate objects are pretty boring.

Hopefully a lot of messing around has made you familar with the Wings interface, so you can try and model something for real.
