I'm using tmux in iTerm2. To resize the tmux panels, I think I'm supposed to press Ctrl+b+Arrows.
For example, if I press Ctrl+b+Down, it shows all the windows in the current app, probably because it catches the Ctrl+Down shortcut.
How can I fix this, so when I hold Ctrl+b+Down (or another arrow key), the panels will be resized?
You'll want to override iTerm's default shortcuts with your own shortcuts to "Ignore".
Go to Preferences > Key and press the + button at the bottom of the Global Shortcut Keys:
Then add an entry for Cmd+K and choose "Ignore" for the action:
This disables Cmd+K.
Just tested this in Yosemite. If you re-map the keyboard shortcut for "Close" in the System > Keyboard > Shortcuts, then that changes the ⌘+W behavior.

The only way to fix this is to turn off or change the global shortcut for Ctrl-down.
You will find it in System Preferences-Keyboard-Shortcuts under "Mission Control".
