tutorial sites
  • blendercookie.com - (recently renamed to cgcookie.com) Oodles of good tutorials ranging from beginner to advanced. David Ward's are my personal favorites, though Jonathan Williamson's aren't bad either. My "goto" site for tutorials.
  • blendtuts.com - Best overall intro to the blender interface I've seen. I'm not sure what sort of accent Oliver has, but it isn't too difficult once you get used to it.
  • http://www.blenderguru.com
  • http://www.blendernerd.com - These are both by Aussies, FWIW. Good tutorials for specific topics.
  • David Ward's Youtube channel - his Johnny Blender 2 and 3 series are pretty great stuff - complete projects from beginning to end without assuming _too_ much knowledge on the part of the viewer. Each series totals in the neighborhood of 10 hours all told.
  • wiki.blender.org - the most "official" documentation that exists. caveat: Not all docs have been converted to cover the 2.5 interface. 2.4 methodology is _mostly_ the same, but not always, and the interface layout differences can be confounding at times. (and many hotkey sequences aren't the same) It's a vital resource, but more of a reference than a tutorial site, though there _are_ some tutorials there.
  • http://www.blenderguru.com/blender-2-5-cheat-sheet - it's a good thing!
textures, materials, reference images
  • cgtextures.com - this is my "goto" site when I need to find a texture for something. Some are really great, some are less so. The site wants you to register in order to download the hi-res versions. They've never spammed me, FWIW, and the preview-versions are useable for most purposes anyway, so right-click/save-image is our friend :^) .
  • Open Material Repository - Not something I use often, but it's handy when looking for something sort of specific and can't get the settings right yourself. Materials download as .blend files. "File/Append" into your own file and enjoy.
  • the-blueprints.com - not bad, not great, but useful. Sorta heavy on cars.
  • 3dreference.org - useful sometimes
  • And, you know, Google is our friend.
models models models
http://www.blenderartists.org - biggest blender-community I know of. Good place to search around on. Plus: lots of inspiring/humbling stuff in the artwork galleries. other programs: Gimp, of course Makehuman http://makehuman.blogspot.com/ - really great program, but it is currently in alpha and _very_ fluid. May require some tweaking for Blender-native export to work right.
