Frances, unless you have another font management program, I wouldn't remove FontBook from your iBook. It can come in very handy if you have a corrupt font that is messing things up. It's only 18.1MB anyway. I'm not sure I'd remove Automator either (28MB) - even if you don't use it, you may find a use for it at some point. Sherlock is part of the system - don't trash that. iSync I'm not sure about.
Generally, I'd be very cautious about apps that get installed as part of the OS (I'm not talking about Chess, obviously) - there is this warning from comments on an article in Ars Technica:
QUOTE
One thing to remember is stripping a code-signed binary (such as all of Apple's Apps on OS X 10.5) will cause the application to be untrusted by the system and you will experience problems with the Keychain and various errors will appear in the console.
The article has a number of suggestions of things that can be stripped out to make room. Read all the comments too - and ignore the trolls.

The ones I'd consider safe to uninstall:
2005 World Book
CD Spin Doctor
Motion Pictore HD
Adobe Photodeluxe 2.0
AOL Instant Messenger
Bud RedHead
Chess
Fairies
Fast DVD Copy
GarageBand
Macam
Marble Blast Gold
Nanosaur 2
ReadIris 7 Pro
Transmit
Tropico2
Question about Transmit though - have you paid for it? If not, no worries. But if you paid for it and don't have it on the iMac, I would install it on the iMac instead. It's a wonderful FTP program - I use it all the time. The built-in FTP in Dreamweaver doesn't always behave - Transmit always comes through. You can also temporarily uninstall it - but make sure you have your serial number in a safe place so you can reinstall later.
Please note the warnings about removing languages - I wouldn't do that, given the issues that seem to arise with MS Office and Adobe apps when you do that.
How much space do you have on the disk now and what is the total amount? How much space do the apps in this list take up?
It might be worth considering using XSlimmer to help slim down your OS X install...
