If you are asking if there is a utility that can reliably identify and eradicate large files that you do not need, the answer is no. Though there are several that will offer to "clean up junk files" for you there is no way for them to know what is required and what it not, what you need and what you don't, and the results can be disastrous.

In addition to Apple's guidance on the matter: Mac OS X 10.6: Increasing disk space, there are some suggestions from Apple Support Communities contributor Pondini that you might find helpful:

btw... Is there a way to keep iPhoto running the way it is in this operating system once I upgrade? I have the latest on my other computer but I don't like the way iPhoto is on it...

For that you have to be more specific: what version to you have and what you find objectionable with the new version. I can find nothing to dislike in the new iPhoto, so I can't begin to guess. The short answer is to archive your old system on a partition or an external disk, so that you can always revert to the old system should you want to do that.
