Congratulations!
At this point I would suggest that you broaden your horizons past the method books. Try some "Easy Piano" sheet music. You could probably play the top melody line, the one with the words. Look for no/1-2 sharps/flats key signatures - and the fewer notes on the page, the better, for right now. If the music has more than one note at a time (like in Hymnals) you could just do the top notes to get you started.
Alfred has supplemental books available - also check out FJH Music, which has some simplified Hymns....

I do have a musical plan for my future and if the Lord allows me to live and continue with my plan, I believe that I will surely find my musical self. I plan to enjoy the remaining of life learning and enjoying music. During the course of all this I hope to leave a legacy behind. When our four children where growing up there where a lot of things that we could not afford for them, well now we can afford to do more things and our children are all grown up and three have families of their owns I have grandchildren. In addition, guess what I plan to add something to their lives that their parents may not be able to afford right now. One of those things will be a music education. Either I will pay for their lessons are teach them myself.
