There are some good bike threads here so search.
Speed and distance, you shouldn't really worry about, but you'll probably need more time then you would for a run ( fitness levels dependent )
As for bikes test ride a bunch, bike seat style are a big factor, type of pedal and shoes is a big decision, when I think about it I know a lot of guys in their fifties and sixties who really messed themselves up unable to get their shoes out of clips/clipless and broke bones or worse.
