Is there a problem if I scan the photos higher than 300dpi? 1

You can scan higher then 300, ITs best to keep all the images
at the same res for that project.
Are you using Quark 4 or 5?

Why would you want to scan higher than 300 dpi for photos? Depending on how they're printed, anything more than 300 dpi is really a waste. You want your images at finished size to be twice the printed resolution, which for most offset printers is 133 or 150 lpi. If it's digital output, you may only need to scan at 150 dpi. So ask the printer what resolution they want - you might be able to save some disk space with lower res pics.
As for the pdf, it sort of depends on what version of Quark you're using. Quark 6 (maybe 5... I don't remember) has a built-in pdf maker. File -> Export -> Layout as pdf. Otherwise, you need to make a post script file and use Acrobat Distiller to make it a pdf.

Sorry but I must disagree on this one 90% of the printers print at 175 Line this would mean you need at least 300 DPI, if you scan at 400 DPI this will also cover the printers whom use 200 line. Newspapers print at 85L, Magazine's print at 133L, Printing on offset stock is 150 to 175L, And Gloss stock 175 or higher.
You as the customer can request a line screen but your printer should let you know which is best for the stock you are using.

It is also appropriate to scan at over 300dpi if the image is being enlarged in Quark. However, it's often better not to go to extremes in either direction. A 300dpi image that's reduced to 10% in Quark only needs to be 30dpi really. If it's being enlarged 200%, scan it at 600dpi instead.
Higher than necessary values are better than values that are too low, but they also take up memory, and may increase RIP time. I've seen people use 30mb files as bullet points, when they could have got away with 800k. If this is done throughout a large document, things can really get out of control!

From a purely production standpoint the answer depends on the job. Ask your printer for the line screen that will be used. Then double that number. Most printers will even tell you the dots per inch as well. 300 dpi is just a cleaner number than 266 dpi (2 x 133 lpi), which is why it is used. It also comes from the fact that Art Directors, Account Managers and clients will ask for images to be enlarged at the last moment and you need to have enough resolution to accommodate that request without having to rescan.
The fact is that 300 dpi in Quark refers to 300 dpi at actual (100%) size. So, if the image placed in Quark is reduced, you can technically resize your image and create a smaller file. Remember that quark keeps track of all the images placed in it and increases the overall file size accordingly. I recommend that if you plan to resize your images, that you keep a copy of the original.
PDF from quark is done in Quark 5 and 6 by exporting the file as a PDF. You’ll find that feature under the file menu. In earlier versions you can get a free extension or save the file as a postscript file and run it through Adobe Distiller. However, in all versions, you really need a full version of Adobe Acrobat with Distiller to allow yourself the full functions for your particular flavor of PDF.
