Marilyn, the screen numbers are for the resolution of the halftone screen used to actually do the printing. Newspapers use around an 85 line per inch screen. Magazines on coated (gloss) stock use up to about 185 lpi. That info and the weight and quality of the paper should not be factors for you to consider.
If the CMYK conversion is being left to be handled by the printer, then no, it's not an issue. If one was doing the CMYK conversion, then knowing the paper helps, though not as much as more detailed information. However, if she's not familiar with doing the CMYK conversion then it's much the best to let the printers do it, since if they don't generally do a competent job they wouldn't stay in business.
