A teacher is best. A good teacher is most efective when you are just starting out, to put you on the right path. It is when you can already play fairly well that you can get by with only occasional lesssons.
If you really, really, can't get a teacher, then alongside learning graded pieces of steadily increasing difficulty I would recommend watching the performances of some of the magnificent pianists that you can find on YouTube. But pick carefully.
I would recommend anything by Arturo Michelangeli - especially his playing of simpler and less flamboyant pieces. Observe how he sits, how he hold his arms, the focussed and efficient movements. If you just soak up good examples like that, then you have a fighting chance of not developing too many bad habits.
It is also important to listen to yourself. If you find that hard then record your performances. notice the diference between the sound you wanted to make, and the sound you actually made. Videoing yourself can help too, as you won't have a teacher to point out when you are not actually doing what you think you are doing! You'll be able to see for yourself! Then sit like Michelangeli and try again!
Finally when you are practising, don't just struggle through whole pieces over and over. Notice the difficult bits, isolate them. Figure out the right fingers to use, and repeat as many times as you have to to get them fluent and sounding right. Practice them, both slowly and as fast as they need to be with separate hands. Alternate right hand and left hand practice. When you are fluent and relaxed with separate hands, put them together, a few bars at a time.
For pieces you could do worse than follow the AB exam syllabus. Alternatively one of the standard piano tutor books will take you in easy steps from total beginner to comfortable at the keyboard. Books of "easy" pieces can be misleading. Often they are not that easy!
Good luck. Playing the piano is one of life's great joys.
Thanks for the advice! I know I will eventually need a teacher but for now its just great to get back into an old hobby I used to enjoy.
I think i'll take you're recommendation and try some of the AB exam pieces so I can gauge what level i'm at. I'm fairly close to nailing 'Le Onde' but I have no idea what level that piece is. And even if I can play it fluently, I certainly dont know all the theory and technique that I would be required to know at that grade.
After watching a few videos of Michelangeli on Youtube, the first thing I picked up on was his posture. I'm normally either slouched or leaning against the backrest (I have to use a desk chair

). As far as the fingering goes, I really miss the little numbers above the notes I used to get when learning as a child

so I just go for whatever is comfortable.
My goal isnt to become a concert level pianist. I just want to be able to pick up and play most pieces I encounter. Sometimes there's nothing more relaxing and better for relieving stress than to sit down and play the piano for an hour.
