[scribus] Images and colors in PDF

I made a proof today in my print shop and there were two minor
1. A greyscale image in TIFF format appeared as CMYK in the PDF.
This means that the printshop must convert this image (and others)
into grey scale (reason: my document is black and white except for
the cover which is in color. The print shop prints the cover
separate from the remaining pages).
How can I tell scribus not to convert greyscale images into CMYK?
Or must I use separate documents for cover and innards?
2. The cover contains text and embedded logo in EPS. Both text and
logo use CMYK=70/0/100/0. In the PDF the color of the text
is correct while the colors of the logo are different. The reason
is the input profile which cannot be deselected.
How can I tell scribus not to use an input profile for images?
Or is there a dummy profile I could use instead which does not
change the colors?
 Open PDF in Acrobat Reader and determinek the RGB colors on screen
using Kubuntus color picker. The input these RGB values into
Scribus or Gimp and to determine the corresponding CMYK value.
The last step is not perfect but good enough to see the differences
in text and logo.
I'm not an expert in color management, though.
Scribus 184.108.40.206 on Kubuntu 9.04 64Bit.
Otherwise scribus works very good, and the scripting with Python
is fantastic - I create all tables with scripts.
