I'd have you pull your elbows back. That seat is not going to be fun for anything other than a prologue, you'll eventually want something TT/Tri specific. Seat angle is something you may end up playing with, goal is not to be sliding forward or feel like your hips are being pulled back. Eventually you'll break the rails on it with that current set up. Wrist angle looks like it could cause fatigue. Giro II or LG Rocket seem to be good middle ground on helmets...to optimize that you really need to test.

That frames flexes like crazy when you get out of the saddle, just a heads up. I've got a rebranded version and I've snapped chains, and had it go into "autoshift" mode when I've been climbing on mine.
