I'm curious, are the spartan suits removable, or are they cybernetically grafted to the people that wear them?

MLOJNIR armor is removable, though it takes a great deal of training to do so. As far as we know, Kurt (the SPARTAN-II who trained the SPARTAN-IIIs) is the only SPARTAN who knows how and is able to take his armor off and put it on by himself; the other SPARTANS know how to take off bits and pieces, but have no idea how to dissamble the torso, shoulder and leg parts.
