If you need the standard InfoPath submit button then you have to enable it in InfoPath. When designing the form go to the Tools menu, then Submit Options and check the desired settings.
The Task Action drop down will only be added to views that are used in client events. Are you reusing the initial view in a client event in an activity in the process?
Does your form have code-behind or otherwise require full trust? Only those need to be approved via central admin; otherwise K2 will deploy the form with the process.
