Congratulations - She looks a completely different machine in black than my blue and white one.
Personally I like my windshield - but I would get out there and get some hours under your belt before you worry about it too much.
Your seat looks fine to me cant be any different than getting on the single Jockey seat that I have where the seat is actually part of the console.
Good luck with her anyway - one thing is for sure the boat will inspire confidence in you every time you take her out. I have had my boat out in some fairly rough stuff and every time I was sure she could handle more if needed.
