We use the Adobe RGB 1998 color space in our labs for use with ImagePrint RIP. Adobe, by default, uses sRGB as their colorspace. When students submit jobs to us, and we open them in Photoshop, should we use the embedded color space (sRGB), use the working color space (Adobe RGB 1998), or not use color management? Also, how do we handle files with NO color profile embedded?

Colour management is absolutely necessary to obtain consistent and results which your clients are happy with. Many headaches arise when the operators of printing labs just don't have a grasp of colour management.
I do not mean to be harsh when I say this, but by the sheer fact that you have asked this question indicates that you haven't quite grasped the idea of colour spaces, colour management, converting profiles, assigning profiles and may not quite be ready to confidently be printing students work to the best quality possible.
There is more involved in this than reading a few posts here on this forum in answer to your question, although extremely helpful, but it may be a good idea depending on your location to participate in a workshop which focuses on preparation for printing. Search around for someone who really knows their stuff.
There are also many books by highly respected authors which will assist in this understanding. Andrew Rodney, [a href=\"http://www.outbackphoto.com]http://www.outbackphoto.com[/url] , and of course Michael Reichmann.
I know I am not answering your specific question in particular, but a suggestion for the future after you have more understanding, would have a list of requirements that files have to be submitted in. Many of the printers and production labs in Brisbane here have a link on their website which explains colour management and requirements for submission of files so you don't have to go through this dilemma.
