Yes. You may as well use the appropiate option in the PDF Export dialog
(downsample images to xxx dpi)

Note that Scribus PDFs are optimized for printing, not for size. I got
nice small files, by
- embedding all fonts, not sepcifying any downsampling in scribus
- running the resulting PDF through pdftops (from xpdf), then through
  ghostscript with appropiate settings

The command line for Linux looks like this (all in one line):
pdftops -level3 -paper match "$infile" - | gsc -q -dSAFER -dBATCH
-dNOPAUSE -sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -dAutoRotatePages=/None
-dEmbedAllFonts=true -dSubsetFonts=true -sOutputFile="$outfile"
-dCompatibilityLevel=1.4 -c .setpdfwrite -

By using the /ebook PDF setting, Ghostscript will downsample images and
the PDF get's real small.
