[Uchiha Sasuke]

Well yeah some of those details were nowhere to be found in the series but you could probably make some pretty good guesses.

1.I image that he was late 20's or early 30's when he built the glove plus krueger was married too even though i don't know why they didnt indulge the point more heavly.I can only make the guess because i image that he was the same age as nancy's (the women in the first movie) parents mainly because they took place in his murder.

2.About his mother after birth.Her detail of very very hard to find.We all knew she was dead in the third movie and probably before the first.I imagine she killed herself from the embarresment and haunting images of the rape.How old she was is kinda unknown.I would say late 30's to early 40's because of her age displayed in the 3rd movie.

Well i hope this helps its pure guess on what i've seen from the movies but its my best explanation.
