Office
Given we're going for a lightweight OS, I suspect lightweight applications are a good idea too.
I like the balance of Gnome Office: fully featured yet lightweight.
sudo apt-get install abiword gnumeric
This provides you with MS Office compatible Word Processing and Spreadsheet capabilities.
For more details, see their individual websites:
Abiword
Gnumeric
Obviously, if you want Openoffice.org (and have the RAM to cope), I'd suggest getting OO.org3 as detailed by Tombuntu.
