That water bottle is weird looking for cycling.

My preference.
Water Bottle: Camelbak Podium, in any case, look for PBA free.

Gloves: You don't necessarily need gloves, many ride without. I'd wait til you get numbness issues or harshness issues and then evaluate the cut and padding. I personally like QI Attack.

Helmet: Bell Volt, you really need to try a helmet on locally, they all have different shapes and fit. Visit your local LBS.
