Need Illustrator help quick!!! :(

[UglyCasanova]

Ok, so I made 30 thumbnail pics that are gonna be 3 x 3, but the problem is I have text and placed images running off the side of the 3 x 3 artboard. There doesn't seem to be a way to clear everything outside of the artboard, so what do I do?

Ok, well everything is done now but I'm still curious how to do it.

Also, is there any kinda of ad on for Illustrator that can generate a page of thumbnails for you (sans everything outside of the artboard :|)
