This point jumped out at me. If the calendar is working for you because of the alerts, then I would recommend putting a few GTD actions in your calendar to help you establish some key habits.

I still schedule my weekly review - mostly to block the time off so others don't book me but also because some weeks my usual time is not appropriate and I want to guarantee I do my weekly review.
You could also use the Intention Journal within GTD Connect to send you reminders (perhaps a daily "Look at your lists" reminder?).
Don't do too much at once and try to be honest with yourself about what you're engaging with and what you're tending to ignore. Good luck and keep posting here - the folks here have great insights and a lot of experience.
