A critical point not made clear is that by releasing the brakes you can help regain traction and help reduce the slip by allowing the wheels to spin freely. Failure to release the brakes, even with ABS, could reduce traction and make it harder to stay on the runway.
Don't forget to plant that sucker, either. You must break through surface tension or slush if landing on a wet/contaminated runway. A gentle touchdown/greaser is not what you want.
I'd also maybe suggest delaying reverse thrust until you're on satisfactorily. It gives you two options: get the aircraft aligned then stop (the brakes alone are designed to stop the aircraft, reverse thrust just takes some of the strain, so no reverse may greatly aid directional control), and if you haven't pulled reverse, you have the option of going around if you keep heading for the grass.
Reverse is an option, not a requirement. Using it limits your options. Consider also the effect of asymmetric/failed reverser deployment (e.g. downwind engine reverser fails to deploy). It's the last thing you want!!!
