I don't think I've ever attempted to answer this question before. The answers will probably change over time for me, as I continue to grow and understand myself, the world and the universe more.
1. I want a holodeck. You know, the Star Trek kind. I'm not sure how much info it would have, but definately TONS. I'd be able to learn languages, study history, build my body, play all kinds of games, live out fantasies and much more. I would be the only one able to detect or use it, and I would be able to use it whenever I wanted to. While in it, I would seem to not exist to everyone else, although time would still pass, so I would still get hungry, grow old, etc. I wouldn't want it to be TOO realistic, because I wouldn't want to completely lose touch with reality, or lose too much interest in the universe outside of the holodeck.
2. I want to be able to read people's minds. I'd be able to turn it off and on. I'm not sure who I'd be able to read. Anyone physically close enough to me? Anyone who I've seen? Anyone in the world or universe? That last one would be another great power in itself, being able to know about everyone alive.
3. A fountain of youth and health. This would also be accessible to and seen by only me. I'd be able to grow old and die if I wanted to, but I'd be able to use the fountain to heal myself and make or keep myself youthful whenever I wanted. I'd still be able to get killed by a bus or a shot in the head. Oh well; I guess I'd just have to be real careful about that kind of thing.
Having no chance at undesired death at all and knowing it would probably be kind of dull.
As for love, I have felt it and will probably feel it again. I don't want to have TOO much control over it, although my wishes (especially the second and third ones) would give me added control over how much I love and what I do about it.
I want to struggle with wisdom and humility on my own, rather than have full wisdom and humility given to me. It's part of the fun of living.
