Can I block spells, stuns and snares?

Spells can be blocked (and consumes stamina) just like blocking physical damage. Knockdowns and such are also avoided (eg, blocking Crystal Frag avoids knockdown). Snare I'm not sure on.

Is blocking omni-directional? Or does it only block in front of me?

Omni-directional.

What is "block casting"? Can I really cast spells while blocking? if so, how does that work?

Block-casting is 'casting'/triggering of skills while holding block, thus you keep the 'block' effect active while performing instant abilities.

While your damage can be reduced, it also eats stamina (particularly if you're a magicka build) and the next update also removes stamina regen while blocking.
