Why would it? Nothing in the readied action section says that you are prohibited from taking those kinds of actions.
Nope.

It depends on how you interpret the rules.
Readying an Action: You can ready a standard action, a move action, a swift action, or a free action. To do so, specify the action you will take and the conditions under which you will take it. Then, anytime before your next action, you may take the readied action in response to that condition. The action occurs just before the action that triggers it. If the triggered action is part of another character's activities, you interrupt the other character. Assuming he is still capable of doing so, he continues his actions once you complete your readied action. Your initiative result changes. For the rest of the encounter, your initiative result is the count on which you took the readied action, and you act immediately ahead of the character whose action triggered your readied action.
Some read the bolded part as meaning "before your next turn", while others take it literally as "before your next action". For those that interpret it literally it would mean that any action whatsoever, including an immediate action, would spoil the ready action as the ready action did not occur before your next action.
Either way you interpret the wording, an attack of opportunity is not an action, and does not prevent your ready action from happening.
Nope. you're all good.
Makes charging someone with a braced polearm a REAALY bad idea.
