grass tracks for the most part are not banked. they mostly (though not all) are flat. part of the fun of grass track racing is that you do typically fast, crowded events on a non-banked course. turns tend to be pretty rough and tumble; slow down and watch those elbows!
also, as per international grass track rules, the only breaks on the field will be coming from the boombox.
cyclocross tires are a good start, the real skill lies in choosing a gear.
