As stated above if you google woodworking or diy woodworking, you'll hit a number of sites and forums. Lot's of great info.
For a couple of years I subscribed to some hardcopy woodworking magazines: ShopNotes, which is now subsumed by Woodsmith Magazine & others. The articles, tips and projects, homemade jigs, assembly techniques were extremely informative. Some of these articles are free on the web. Entire, searchable dvd or web-based sets of articles are searchable available at reasonable cost.
Another great source of info is vintage tool manuals, available free on line. I've downloaded vintage Craftsman manuals for table saws, routers, jointer/planers, etc. Lots of useful tips and safety pointers.
Power tools are very dangerous, and can do their damage in a fraction of a second, well before any person can react in defense. Lots of safety footage on youtube for all types of tools. Fear itself should be overcome, as it may cloud judgment. Healthy respect and prudence are called for.
Some general safety concepts
Though seemingly obvious, always keep your hands & fingers well away -- at least 6" -- from blades or bits. Clamp workpieces to a solid bench so you don't have to hold them. For a stationary tool, like a table saw, use a fence or miter gauge, and push sticks, maybe a featherboard to guide small workpieces to keep your hands away from the blade or bit.
Maintain good footing and balance. Never stand so that you can fall onto the blade or bit.
Table saws and drill presses, etc., can spin or throw things with unbelievable speed and force, faster than a person can react. (This includes arbor chucks accidentally left in a drill or lathe.)
