How can I make ctrl+right/left arrow stop changing Desktops in Lion? ⌃ Control+→ and ⌃ Control+← switches desktops. 

I actually had this enabled in Spaces on Snow Leopard, but I'd like to turn this off because I use those key combinations when editing in Eclipse. How do I turn this off?
Go to System Preferences > Keyboard > Shortcuts > Mission Control and change the settings for "Move left a space" and "Move right a space" or disable them completely.
