I like to convert to ProRes422 on a Mac with 5DtoRGB Batch. Then even though I started with 8bit footage, I am in the 10bit colorspace for color correction, transitions, effects, titles, etc.
With Premiere you can work with the h.264 natively but ultimately it has to be rendered. So that said, you can render at the beginning of the edit or render at the end of the edit, but you will have to render.
