comment How can we obtain equations of motion from $\iota_{X_{H}}\omega =dH$?
Echoing @Uldreth's comment: $\iota _{X_{H}}\omega =dH$ is an identity, or alternatively, a definition of the Hamiltonian vector field $X_H$. It contains no further information.

comment What canonical momenta are the “right” ones?
@ACuriousMind: Thanks for the corrections. Regularity assumptions are implicitly assumed, but even with them, it seems messy to write down a complete proof.
