Replying to Knee surgery tommorrow.........

hey guys,
so im goin in for surgery tommorrow for what theyve diagnosed as a torn acl and meniscus tear, my knee feels pretty good tho so im hoping it wont be as bad as the diagnosis. but regardless it will be a long rehab and im missing my junior soccer season and prolly this whole ski season. needless to say, it sux balls. however, looking ahead ive got some questions for those that have had it done:
is it possible to make it back before 6 months in like 5-5 and a half months if you hit rehab hard?
how long were you on crutches for?
what was the hardest part about coming back?
how do you know when your ready?
if im going in tommorrow, what are my chances for being 100% come early april for baseball season?

any answers or just general advice about similar injuries/rehab would be greatly, greatly appreciated. thanx so much
