No, as long as your feet don't cross the baseline, your fine.
*Note- do not catch the ball with your racket if you decide not to hit your toss. If it touches the racket, it counts as a serve.

Yes. In fact, most people do jump on a service in tennis. You just need to be carefule that your foot doesn't cross the baseline early so you avoid a foot fault.
It is illegal to jump the turnstile.
Jack Cascio shows you in this video how you can jump higher and dunk.
Put your foot (any part, even if it's toes) outside the jumping line, and you get a "fault", or an illegal jump.
The best types of serves are either a jump float or a jump serve.
Only while you're actually on active jump status. If you're jump qualified, but serving in a leg unit, you won't receive any extra pay.
