syncing google docs/calender etc. to ipod touch

Hello,
Is there a good application that lets you view google docs/calendar/notes in your ipod touch. I have just bought an ipod touch and I am wondering because I have a few lists i want to put into my ipod touch. Instead of doing that I figure I could type them in google docs/calendar/notes etc. and then sync them to my ipod touch.

As well, I would like to then be able to download them for offline view and edit them. I'm not sure if there is a few apps combined/or one app. I'm not even sure if it is even possible. Trying to make my ipod touch useful as a organizer basically.

Any help would be greatly appreciated!

Thanks,
Qua Sar

can that sync to the touch and back to google docs?

I got the gmail email to work right. But when i add something on the google calender on the touch it doesn't get pushed to the calender. As well I am unsure how the notes syncing works. Any help would be appreciated!
