  1. A. Use the equation Q = C*V

    You don't say if the capacitors are in parallel or series. If in parallel, V = 1700 V for each.

    B. E = (1/2) C V^2

    Your second "part B" must belong to a different question. More facts are needed about capacitor size, capacitance, and whether the Teflon fills the gap.
