You seem very determined. Remember to have fun. Also be aware that the fundamentals of grip, stance, sight picture/alignment may vary slightly in how they are applied due to your specific firearm. You're shooting a single action revolver correct? Should you branch out to double action be sure to train for the long trigger pull. The necessity of a firmer grip may become apparent when you shoot a larger caliber. But with your enthusiasm I have no doubt you'll find your answers as you come across the issues.
If you can spare a few hours, I took an NRA first steps pistol class which was very comprehensive and relatively cheap. I had been shooting for a few years and still learned a few good pointers.
