What's up NewB? The best thing that you could do right now is to learn the 1, 4, and 5 of every key. For instance, in C the 1 is C, 4 is F, and 5 is G. These three chords are guaranteed to get you through almost any song out there. There are, of course, added chords but those come with time and lots of practice. Get the progressions down smoothly in every key and that will enable you to play in all your keys (even B). That will give you an advantage as many "great" musicians cannot play in every key. Transposition is a handicap. Lastly, let God lead you in all of your playing. Be blessed and Stay Anointed!
