I know this is a kinda old thread, but I just wanted to mention that FSX has Antiskid modeled in. You have to assign a key combo or joystick button to make it operate though. It doesn't have anything assigned to it by default, so there's no way to activate it without assigning a key-combo or joy-stick button to it. The FSDT FSX BA F/A-18C v16.1 does have a switch in the VC cockpit for it that works very nicely. The default F-18 might too, but I am not certain. Don't use on the carrier though That might help the whole "ice-skating" problem.
And like Chuck mentioned, let the speed-brake do it's job. I use it down to about 65kts. I use aerobraking too. Hold the nose off the ground as long as possible. It helps you slow down faster, if that makes sense. Those big huge stabilators do make a lot of drag.
Hope this helps a little bit...
