Library clean up

I've got an SSD and need to make some more room.

My two libraries, /Library and ~/Library, seem to have some candidates for removal. But past sad experience has taught me that sometimes removing something there, even when I don't use it, can make some applications unhappy. Wouldn't want that. So, some questions since others may have gone down this path.

Garageband has a bunch of music, GBs worth. I rarely use it. Can I just nuke those? I'd move them, so they could be moved back.

/Library/Audio has iLife audio and again, Garageband. Chuck it?

iTunes has a bunch of stuff, but I'm wondering about MobilSync since I have a ton of apps. Can I redirect backups to an external? or even just manually move these?

Google has a also left a ton of stuff, most apparently related to Picasa, like previews. Again, couldn't find an easy way to redirect it. Any ideas?

Adobe is also a ~/Library pig, and I'm working on that. It leaves tons of old stuff behind every upgrade.

Any other suggestions would be appreciated.

Look in "/private/var/vm" without the quotes, and check for a SleepImage file.
If you find one, do a Get-Info on it and check the size, these can often be as large as your installed memory.
Now if you are willing to sacrifice Apples "Safe Sleep" feature for just plain old fashioned sleep you can reclaim this disk space with the following commands entered into a terminal window.
Follow each command by the 'Return Key'
Set sleep mode in shell:
sudo pmset -a hibernatemode 0

Remove the image:
sudo rm /private/var/vm/sleepimage

Create a blanked file:
sudo touch /private/var/vm/sleepimage

Make file immutable:
sudo chflags uchg /private/var/vm/sleepimage

Thanks; good idea but I'm using a hackintosh so no sleepimage, just swaps.
