I read somewhere that it is equal to h (Planck's Constant). How much merit does this information hold?

None.

h is the quantum of action, which does not have the units of energy.

For a photon of frequency nu, the quantum of energy is E=h*nu. Thus it can be arbitrarily small for sufficiently soft photons.

If quantum mechanics is based on the fact that the universe can be quantized and we haven't quantised time, space, matter or energy yet... Why do we call it quantum mechanics?

This is puzzling. Quantum mechanics also produces BANDs of energy (i.e. a continuous range of energy) in matter that forms the conduction band, the valence band, etc. in metals, semiconductors, and insulators.

I suggest you stop getting hung up on the name, and learn the physics.

Although BANDS are only truly continuous within the unphysical assumptions of condensed matter on a lattice. Infinitely many periodic, perturbative potentials. To me I always assumed surface effects would produce some level of coarse graining in real systems.
