PDF issue with font embedding and pictures

I have a large file in a word document.(192 pages). I saved this document as a PDF and submitted it to Ingram Spark for publishing as a print book. They have replied with the following message: FONTS NOT EMBEDDED IN THE PDF: We require that all fonts be embedded. Please submit a new file with all fonts embedded. You may refer to the File Creation Guide for further instructions on creating a compliant PDF. PDF CONTAINS ICC COLOR PROFILES: We request files with no color profiles assigned. Please convert all colors to grayscale for black and white images, or CMYK for color images and remove all color profiles. Saving a new PDF with the default setting of PDF/X-1a:2001 will address the issue. For best results, please correct the issue(s) listed. You may refer to the File Creation Guide for further instructions on creating a compliant PDF. I would like for these two issues to be resolved. I have used Styles, however there are still some problems with some of the fonts not embedding properly (I think that there must be some hidden ‘spaces’ that are in times new roman and arial that I can’t find. I tried to resolves this myself but I can’t). ie This is a job involving problem solving, not just ‘embeding’ as I tried to do this and it didn’t work for me. For the pictures issue – all of the photos and diagrams I would like to have in colour. I would like you to save the new pdf under the default setting of PDF/X-1a:2001 I can supply the word file or the PDF file. If the PDF file needs to be created in your program, I would like to be sure that it does not change the formatting of the tables in the back chapters. This has occurred before when I have used some PDF creation files. Ie I don’t want the above two problems resolved, but new problems created in the formatting. Outcome: A PDF file that has none of the above issues.
