Each map item can have it's own map extent/scale and you can lock the layer list, by pressing the "Lock layers for map item" to prevent live updates from the main project window. I would recommend using the latest trunk version, but the 1.4 may have this option already.

Can you open the GRASS toolbox and switch to the Browser tab. Then open the vector section, and click on this imported vector. On the right you should see a table similar to below. Please either post a screen shot on the web somewhere, or you can copy/paste the text into a mail message. Send this to the qgis-user maillist and we can try to understand what is wrong. While you're at it, grab the same table of info for the raster, and post that as well...
