Theres quite a few nice tutorials that cover the basics over at
www.newtek.com , also take a couple of ours to just explore the interface and see what every tool does, then when you feel you got a pretty good hang of it rush back here and download the awesome tutorials this site have to offer, I found that video tutorials gives alot more than a book can offer.
btw. welcome to the wonderful world of LightWave
Hope this helps a bit
