If you know how to use Vi then use and edit the files locally as described below else copy them to the SD-card.
From a terminal do the following:
su
cp /home/zaurus/Settings/AddressBook.conf /mnt/card/AddressBook.conf
Now put the SD-card in the PC cardreader and edit the file AddressBook.conf on your pc and change the following:
Category0 = Work Phone
Category1 = Work Fax
Category10 = Home Zip
Category11 = Home State
Category12 = Home City
Category13 = Home Street
Category14 = Birthday
Category15 = Work Country
Category16 = Home Country
Category17 = Work Web Page
Category18 = Home Web Page
Category19 = Work Mobile
Category2 = Work Zip
Category20 = Work Pager
Category21 = Anniversary
Category22 = Nickname
Category23 = Middle Name
Category24 = Spouse
Category3 = Work State
Category4 = Work City
Category5 = Work Street
Category6 = Emails
Category7 = Home Mobile
Category8 = Home Phone
Category9 = Home Fax
Also in the same file change the Items section to this:
Items = Work Phone,Work Fax,Work Zip,Work State,Work City,Work Street,Emails,Home Mobile,Home Phone,Home Fax,Home Zip,Home State,Home City,Home Street,Birthday,
In the same way as describe above copy the files described below and do the edits described.
In /home/zaurus/Settings/qtmail.conf and /home/zaurus/Settings/qtmail_account.conf change "accountname = Synchronization"
In /home/zaurus/Settings/sharplist.conf there's a line 'strings=' -- fill in a semicolon-delimited list of some good default schedule items.
A bit farther down is a list of some default to-do list items. Again, erase the Japanese and fill in that strings= line with some default items.
Also, in /home/zaurus/Settings/todo.conf change FontLogicalSize=0 to FontLogicalSize=-1 to make a bit more room in the To-Do applet for English text
When all done copy the files back using the same manner in reverse, like this:
cp /mnt/card/AddressBook.conf /home/zaurus/Settings/AddressBook.conf
