How to correct uneven gum line, off center teeth, and one uneven tooth? (photos)

I stumbled across this site and saw some great advice, so I thought I'd get some opinions from professionals! First of all, my gumline is uneven above one tooth. The same tooth with the uneven gumline is actually the center of my smile. Also, the tooth beside that one (not the other front tooth) is tucked back a little. I took a picture from an angle to try to show it better. How do I fix the off center teeth, uneven gumline, and the one tucked back tooth?
