calling all gardeners!

I'm looking for a good reference for first-time gardeners.  I wouldn't say I'm ready to go gung-ho, but so far I've kept up with the plants I've planted and I'm actually paying attention to them; I think I'm ready to start learning.

Anyone have any suggestions?  Books? Magazines?  Websites?

Also, can anyone tell me what this is?  Is it wild onion?  Wild garlic?  Flowering alliums?  When I pull them up or break off a stalk they smell like onions, but the internet is telling me wild garlic.  They're in the flower garden and I'm not sure if I should be cursing them or thanking nature for them.  Or eating them.

In the ground.  They're the tall ones in the center of the picture.
