Don't force the landing. Let the nose wheel come down gently if you can. It is unusual for the nose of a tricycle gear aircraft to want to come up after landing because the centre of gravity on an aircraft with a nosewheel tends to push the nose downward. Maybe you aren't reducing the throttles to idle?
Modern Boeing airliners have spoilers that can automatically deploy on touchdown and these will kill any lift. You'd usually set the speedbrake lever (found to the left of the throttles) to the "Armed" setting before touchdown to make this happen. Spoilers/speedbrakes look like doors on the top of the wing and add a lot of drag and reduce lift. The speedbrake lever can be pulled all the way back if you need to lose speed while descending (particularly approaching 10,000ft and the speed limit of 250kts). For landing, they would be returned to the armed setting to auto-deploy on touchdown.
Braking is well catered for on something like the 777. Autobrakes will apply gentle braking on the wheels after landing. I find the setting "1" is usually adequate. Pressing "b" to apply brakes disconnects the autobrakes. You also have thrust reversers which you can deploy after landing: pull the throttles to idle and press "delete" to engage and disengage. There's usually no need to panic and start reversing thrust and braking hard if you land on the landing zone of the runway. It will slow down.
Also is it ok to apply rudders once the rear wheel have touched, but not the front wheel. Upon landings the plane tends to go in the "left" direction and that's where another "wayward going" mess up happens if you are on the keyboard and not the joystick with throttle and rudder paddles. What are other ways, if any, to give plane on ground the direction without using the rudders.
Yes. Rudder would normally be applied throughout the landing and during roll-out (transition from landing to taxi). If you've been flying in Europe this week and using real weather, it's been very windy. The turning tendency on a jet aircraft usually comes from the weather-vane effect, where a crosswind from the left pushes the tail right and the aircraft pivots around the wheels making the nose go left -- like a weather-vane. Once the nose wheel is down, you get some steering capacity but, until then you may need rudder to keep it straight.
The rudder is the primary control for direction immediately after landing but the aileron is usually directed slightly into a strong crosswind. A joystick with throttle and an axis for the rudder makes all of this a lot easier (but you can still enjoy flying without one).
