You know, you really don't need filters to take pictures with your camera!
The closer the moving subject is to you, the faster shutter speed you'll need to freeze motion. Bump up your ISO as needed, to allow for faster shutter speeds. Likely you'll need 1/1000 or faster. I'll assume a middle f-stop, such as f8, so on a normally sunny day you'd need ISO 250 or so, to get 1/1000. Might want to go to ISO 500, 1/1600, f8, or even faster, though. Experiment and make some notes. A big part of photography is trying things and figuring out what works and what doesn't.
You can focus manually, pre-focusing on the point where you will be taking the photo. Start panning with your subject before that (without changing your pre-set focus) and smoothly track it to the point where you take the image, continuing on past it after tripping the shutter, in a smooth panning action.
If you choose to use auto focus, yes you would want to use AI Servo. You'll need to hold the shutter release button halfway down to keep AF active as it tracks your subject. I'd manually set just the center AF point, it's the most sensitive and should give the best results. Your subject might end up "too centered", but you can crop the image a little later on in your computer.
Also do a search here about "back button focusing". That's a technique many sports/action shooters use, separating the AF function from the shutter release button for more precise control over AF.
The lens and camera's AF perfromance will both be a consideration. USM lenses, lenses with big apertures (f2.8 or larger) are generally faster focusing. Different camera models also have faster or slower AF performance.
Frankly, if it were me I'd shoot a lot of slower shutter images, too. I get kind of sick and tired of all the "frozen" sports and action images. I just think they get pretty boring after a while and prefer to mix it up, allowing for some luck or chance to slip into the process. Often when shooting a job I'll get the obligatory "frozen action" shots in the can, then start doing some things outside the box... A well done, panned image with a slower shutter speed can show an interesting rendition of speed and movement, IMO. For that sort of shooting you might want a tripod, perhaps a gimbal mount and possibly even a flash.
