Trading software / news analysis

I'm trying to learn more about trading and thought these forums were a great place to start.

I know I'm an newbie, but I greatly appreciate any help.

1. What are the best trading software applications, and what is their range of pricing per month (not including hardware or commission)?

2. Are there any applications or sites that incorporate news feeds (like Reuters or Dow Jones), and if so do they analyze the sentiment if news is positive or negative?

I'm trying to build a strategy around divergence in price from the sentiment of the mood and wanted to see what was out there.

Thanks!
