There are a ton of resources out there for sales professionals.  You could easily drown yourself in books, articles, blogs, and podcasts.  Below are some of the resources that I recommend.

Blogs

I work with Johnny and love the insights he provides on his blog

Podcasts

Advance Selling Podcast – Bryan Neal and Bill Caskey have been producing this Podcast for a long time. I go back and listen to a number of their podcasts over and over.

Sell or Die – Jeffery and Jennifer join forces to create a great podcast that interviews other salespeople and can provide you with a wealth of quick, in-your-face information. You will find Jeffery Gitomer on a number of my lists.
