A quick vid of serves. The first one is a flat while the next serves are attempted topspin/kick (i know there not great lol)

Things i thought i should work on/observations
1.) jumping into court an not
spinning on left leg
2.) maybe
slightly higher toss?
3.) getting my
left foot in front of right foot during pinpoint stance (like the lockandrolltennis teacher)
4.)
Trophy pose doesnt look right either (idk why? maybe racquet arm doesnt drop enough?)
I want to get a fundamentally sound serve in approx two months if i can! Been working on my serve forever so hopefully its not so terrible
"You are only as good as your second serve."
There are two keys to a kick serve that will let you hit it different from your "flat" serve:
1. Toss almost over your head.
2. Bigger shoulder turn.
You'll have to work on tossing to this location.
Your biggest problem right now is that with your pinpoint stance step up, you are swinging your back shoulder forward into the court way before you should be.
Watch this video from "The Serve Doctor" starting at 3:50 into the video on how to hit a topspin serve, and the need to use a "bigger shoulder wind", and to maintain that until the forward swing starts.

I will address your 4 questions with responses below:
[As Tennis CJC mentions you've got to keep your tossing arm going up in a "follow through" of your tossing motion until it is straight up, and keep it straight up above you until you start the swinging motion to maintain your balance as you wind your shoulders back more into your trophy position. This should fix your concern about your
trophy position.
See pics 3,4 below. And see pic 4 for how steep the shoulder angle between the front and back shoulder should be in your trophy position.
]
[Because you don't get a steep shoulder angle, as you swing,
you are swinging your shoulders around mainly from right to left. If you can get that high shoulder angle, then the primary direction of your shoulder movement should be a
vertical reversal of your shoulder angle so your back shoulder moves almost straight up and your front shoulder almost straight down, as seen as pics 4-8 above.
This is discussed as so very important in this video:

When you learn to develop a vertical "shoulder over shoulder" action, you will stop
spinning around on your left leg, as this is just a symptom that you are spinning your upper body/shoulders around with your current horizontal shoulder action.]
[A very slightly
higher toss may be necessary to allow yourself to wind your shoulders back further. But don't make it so high as to develop a hitch in your swing.]
[The
further forward you bring your rear foot, the more difficult it is to maintain the "big shoulder wind" you need for a topspin serve. So that even though you get a "tighter wind" all the way through your body, the difficulty in balancing may lead to more difficulty mastering the serve. (Djoker and Fed are at least two current players who think the added stability of a platform stance outweighs any advantage of the pinpoint, but you decide for yourself.) If you do keep your pinpoint, notice in the above posted video of Sam Stosur's
kick serve
http://www.youtube.com/watch?v=qnqYduBcmNQ that she has a relatively small step up with her rear foot, and keeps it to the left of her front foot to help maintain her shoulder wind/balance.]
