I find the workspace switching keybindings given in 
XMonad.Actions.DynamicWorkspaces easier to understand:
myKeys =
  otherBindings
  ++
  zip (zip (repeat (mod1Mask)) [xK_1..xK_9]) (map (withNthWorkspace W.greedyView) [0..])
  ++
  zip (zip (repeat (mod1Mask .|. shiftMask)) [xK_1..xK_9]) (map (withNthWorkspace W.shift) [0..])

To use the F keys, you want to change the list of keys [xK_1..xK_9] to 
[xK_F1..xK_F12].

There might be a way to convert it to not use withNthWorkspace, but it will 
probably look more like what you had.

It doesn't look like it is immediately achievable from the config, but 
someone more knowledgeable may think otherwise.
