Grindcore is a more faster tempo with the drums etc, the lyrics are more political in nature as well. Vocally it's more of a scream/growl combo.
Start with some Napalm Death (whose second drummer apparently coined the term) then Brutual Truth and Carcass.
Deathcore is more slower in tempo and can have a mix of subjects. Recommended starters are Dying Fetus, Repulsion and in a roundabout way Cannibal Corpse.
