There are a couple more things you can do besides making sure the gear is down before landing and using reverse thrust after landing.
Go to the knee board, select check lists and scroll down to the landing checklist. One of the items in the landing checklist is to arm the speed brake. The key command is Shift/ (shift forward slash). If you want to see just what this does, select the throttle quadrant, hit shift/ and watch the control lever that says brake. Shift/ only "arms the speed brake" when the plane is flying. If you're on the ground shift/ will act just like hitting / and deply the speed brake.
That's not the wheel brake, its the speed brake. To see what the speed brake is, when flying select outside view, zoom in on the wings and hit just the / (forward slash) and observe the speed brakes deploy.
The speed brakes should deploy automatically once you touch down when armed. That is the first thing that will help you slow down. Once the nose wheel touches down, reverse thrust, and then apply the wheel brakes after 80 knots or so.
This may sound like a lot at first however all these things will become second nature once you do them often enough. To stop REALLY FAST you can also set the auto-brake to Max on the panel switch that has settings RTO,1,2,3 or Max. The RTO is for take off and the other settings are for landing.
Depending on your preference, you can use all three methods all the time. Personally, since the auto-brake won't release until you tap the brakes in FS, (I can't speak for the real world,) I don't usually set it. I just go with the speed brake, apply reverse thrust until 80 knots, then use the wheel brakes to slow enough to turn off on a high-speed ramp, if available.
You probably know some, most, or all of this.
I just thought I'd mention them in case you haven't read about them yet.
The only dangerous part of flying is landing.
Flying is the 2nd greatest thrill known to man, Landing is the 1st!
EDIT: Opps, there is no auto-brake in the Lear. I was thinking about the 737.
