The "bump" on the nose is an air-to-air refuelling pod and various other lumps and bumps are chaff/flare dispensers and/or electronic countermeasure pods. The aircraft also has its own air stairs towards the rear for the entourage and the chappie that carries the "football", which is a brown leather bag that contains all the nuclear launch codes.
The aircraft are based on the 747-200 so would have the analogue flight deck. They used the -200 for a reason because digital equipment is vulnerable to EMP (Electro Magnetic Pulse) which is given off during a nuclear explosion.
