I can help (hopefully) with the singing and control. Believe it or not, HUMMING really helps to give your vocal chords a work out. When you're traveling in your car or sitting at home, try humming loudly. Choose a song that you like and that you feel is a challenge for you. Not too much of a challenge, but just something that will make you work. Do this for about a week, then while humming, pick a few words out of the song that you open your mouth and sing, and intermittently switch back and forth from humming to singing certain words or verses. It worked for me. You'll be surprised at the difference in control you'll have developed. Let me know how it goes! L8r!
