If you have a lot of texture detail, don't import it as a .svg file. You'll end up with thousands of points/nodes which will take you hours to edit. Honestly, it's better to import a bitmap and re-draw it in Anime Studio if you want a vector drawing. I didn't believe it when I started with AS but it's true...

Yes. You could have a file, say, 600x320 pixels and export a 300x160 pixel version. In one of Anime Studio's sister programs, Manga Studio, comic creators often work in print resolutions (300 pixels per inch and upwards), but can still export to web resolution (75-96 pixels per inch) if required. That way they get the best of both worlds. You can do the same in Anime Studio.
NOTE: Don't forget -- if you are going to zoom into a bitmap in AS, or intend to use a close-up, increase the bitmap resolution accordingly.
You can't have everything. Where would you put it?
