ball toss: if it goes to far out in front of you or not high enough then you are letting it go too early. if the toss is going behind you then you are tossing it too late, you just have to practice. as for hitting it where you want to, before you hit it bring the bal and your racket up in front of you and aim it in the direction you want to hit the ball. also on your serve bring the racket back down behind you and then bring it up. people you take it up straight away are losing out on a lot of options.
in regards to how long it took me to start 'serving like a pro' and you put it, i started 'serving like a pro' from the very first time a picked up a racket. i haven't once lollipoped a serve except for when i've been coaching little kids and we had a coaches challenge.
