The information your newspaper gave you was absolutely correct and at the same time absolutely useless. :-)
I'm assuming for a moment that your ad was sent as a CMYK PDF and created in something like Adobe InDesign or Illustrator...hopefully, the text portion, it was not created entirely in Photoshop.
The text portions should have been provided as "vector" art and not rasterized down to 300ppi (read: BLURRRRY). Text and other design elements should in their "native" vector format so the resolution will come out at the maximum resolution of the newspaper's output/plate imaging system....this would generally be in the range of 1200-2400dpi at perhaps 85-133 lines per inch screening.
As far the photographs placed in your ad (placed in InDesign or Illustrator), 300ppi should be fine for newsprint. What's MORE important is the profile used for separating the image to CMYK. Newsprint/newspapers have very low total ink requirements (200-240%) and relatively high "dot gain" or TVI. The correct answer here would be to use the CMYK ICC profile that they recommend...but in the current version of Photoshop CS6, there's a profile labeled "US Newsprint (SNAP 2007)"...that profile would be at least a good starting point and be light-years better than the non-information they gave you. As far as 8bit vs 16bit, if it were me, once I've converted the image to CMYK, I would change to 8bits-per-channel mode and then place it in my InDesign or Illustrator document. (Side note: make sure you have InDesign/Illustrator set to IGNORE embedded CMYK profiles (Preserve Numbers) or the image could get hosed when placing it in your layout...and export to PDF with No Conversion).
Summary:
* Text should NOT be rasterized to 300ppi or it will be blurry when printed.
* Images should be separated using a suitable ICC profile for newsprint publication.
Regards,
Terry
