The best right direction for a lot of people is a real live teacher. Now you have, possibly, both time and money (I hope!) this is one of the best moves you can make. As long as you can find a teacher who is sympathetic to your way of learning, and understands how you need to learn, it'll be a success. All the time, questions will crop up, and doing things via the internet often won't find you the answer that you need. A lot of internet stuff is good, very good. But there's also a lot of dross, and misinformation out there.
Finding that teacher is one of the biggest hurdles - ask in music shops, local schools, friends, anyone you know who plays. Depending on what style you'd like to emulate, you could try sites like ABRSM, with their exam systems, but also local teachers. Musicians' Union also has lists of teachers/performers. Good luck - enjoy the journey!
