I'm pretty sure everything you are having problems with is completely normal. It all just comes with practice.
You have will soon be very experienced with doing the Superman, when out in decent winds. This is the first trick most people learn and you will entertain anyone who is watching. Just make sure your boardies are done up tight

.
Also when I was learning I was great at over estimating the wind speed just to get out on the water..."Yeah this should be enough" will end in "omg why can't i get up on the board, I must be doing something wrong". I was having huge problems getting up on the board until i went for my second lesson in 20+ kts and got up on the board straight away.
Make sure you can body drag upwind before you go in deep water, this is pretty obvious but it can get very tiring in heavy chop, especially if you end up swallowing lots of ocean. It's not a nice feeling being pulled into shore while your brand new board isn't moving.
Oh and one more thing, this is also pretty obvious, but just in case...when you are in water never EVER panic. I had my kite hindenburg on me once resulting in me being covered in lines and im 100% sure if i had of panicked and started flailing around i would have drowned. Things get nasty very quickly on the water.
Have fun and enjoy the days of watching for increasingly larger tree's moving.
