TWO CONCERNS:
1- The brake light switch actuates the park lock solenoid. Therefore, if the brake lights arn't coming on because of the switch, you won't get it out of park. Replace the switch or have it checked for replacement.
2- The fact that the pedal goes to the floor indicates to me there is another problem with the brakes. To me my first guess would be the master cylender is going bad. Check around on the ground and behind each wheel for leaks. Also, make sure the rubber brake hoses are not expanding when the brakes are applied.
Let me know if you have other questions.
