No big deal - radial or bias - from my experience. Slick versus treaded? Again, no big deal, although the less distinct tread patterns will be a bit less likely to heat up excessively - I think.
But first of all -- your tires are not just to the speed you'll be running, but to the speed of the record in the class you're going to run. If your bike will only go 130 but you're running it in a class where the record is 205 -- you'll need tires that'll meet the 205 number, not the 130.
