If you want some more advice about printed graphics, shading/drop shadows are truly hit or miss. If you look at most professional logos, they are very crisp/clean with only using about 2-3 colors. If they do have a logo with shading, you will also notice they typically have an alternative logo that is simpler. This allows their logo to be used in various processes and saves a lot of money. Example: McDonalds does have shading in their logo, but if you look at a McDonald shirt, it will only have red, yellow, white. This allows the embroidery costs to be dramatically decreased. Google is another brand with a drop shadow, but you will notice their logo in alternative medias can be flattened easily.
Your logo will flatten easily as well, so I'd suggest having whomever designed it, provide you with the logo in a simple fashion as well. Tell them to make it 20x larger than you will ever need, and save it as a high resolution JPEG/PNG & EPS. That way, no matter what the project, you will always have the artwork you need.
