I disagree about splitting them.
I did all three on my LT and had no problems with leaks. Get the OEM rebuild kit. It has everything you need. Just make sure things are surgically clean before putting them back together and use some clean brake fluid to lube the pistons before pushing them in.
You might consider also replacing the brake line as, they can get rubber flakes on the inside that cause them to act like one way valves.
I never pulled the MC on mine as there was no problem so it's up to you. If rebuilding the caliper doesn't solve the problem, that's the next step in addition to replacing the line.
