If you're designing only in Illustrator and it's all vector you should leave it all vector and not bring it into photoshop before output. If you want to mix vector and raster elements it's still best to leave the vector alone (un-rasterized) until final print using one of the following: Illustrator links (to bring raster elements in to Illustrator), Smart Objects in Photoshop (to bring vector objects in to Photoshop), or my preferred method of using InDesign for final assembly. By keeping vector elements vector all the way through to the print you won't have to worry about resolution on those elements and they'll be as crisp as your printer/rip can produce.
I also consider 150ppi to be the baseline for wraps on raster elements, shooting for higher when possible. I don't really believe in overkill, even at distance. When the opportunity presents I render out raster graphics at 360ppi but I'm crazy like that.
