Yes, President Kennedy did increase the number of advisors and aides to South Vietnam, in an attempt to prop up the unpopular leader, Ngo Diem
Ex-Comm was the specific group for the Cuban Missile Crisis
US Army General Maxwell Taylor went to Vietnam, and on 01 November 1961 wrote a letter to President Kennedy recommending US Troops for Vietnam.
No. President Kennedy sent advisors to South Vietnam, not Korea. Vietnam was the slow-growing cancer that allowed advisers to become involved. JFK sent the SEALS and Green Berets to Southeast Asia (Vietnam). JFK authorized the "Green Beret" for the US Special Forces. The SEALS were converted UDT men (Under Water Demolition men, aka Frogmen); they too were converted to SEALS on JFK's watch.
After President Kennedy was assassinated, President Johnson continued the same foreign policy of sending advisors to Vietnam. The advisors requested ground troops to the area, but Johnson refused until 1964. Three Vietnamese gunboats opened fire on the USS Maddox, stationed in the Gulf of Tonkin. President Johnson met with advisors to create a plan of retaliation.
A group of advisors hand-picked by President Kennedy to help him handle the Cuban Missile Crisis. EXCOMM is short for Executive Committee of the National Security Council.
The first "advisors" were sent by President Eisenhower on 12 February 1955. On 13 May 1961 President Kennedy sent the first Special Forces troops to Vietnam. In March of 1965 President Johnson sent in two Marine Infantry Battalions.
Kennedy Since there is no clear absolute date for the beginning of the war, we could say President Eisenhower or Kennedy. There were advisors there during the Eisenhower presidency (1953-1961) but combat troops were sent in during the Kennedy/Johnson administrations (1961-1969).
President Kennedy sent only advisors, arms, and money into South Vietnam, President Johnson escalated the war and committed U.S. troops.

At first he sent in about 50 military advisors. Later, he expanded this to more "advisors" and even military troops.
