CSS3 features in IE8

Question

css

Actually, I'm interested in the question of correct replacement of the CSS3 feature for IE8, I'm especially interested in the replacement: border-radius, text-shadow, box-shadow, and also a gradient ...

Maybe there are some Js scripts or something?
PS for the gradient and shadows, as I understand it - filter ...
