There is an app called "Things" (which is like pretty much a Tasks.app) this can sync with iCal which I sync with Google Calendar - that I sync with my iPhone using NuevaSync. Note I don't use Outlook, but if it supports caldav this whole thing should work. All that being said, right now it looks like Google Calendar doesn't support writing "To Do's" over caldav I get this error "HTTP/1.1 403 Google Calendar doesn't support storing of "To Do" (VTODO) components" to operation CalDAVWriteEntityQueueableOperation" But maybe, this feature will shortly be enabled.
