I sue Goodreader on my iPad to read material for the course I'm doing at the moment and thought this may be of use.
If you turn on wireless sharing in Goodreader you can map a network share on a mac to your iPad using the instructions here http://www.goodiware.com/gr-man-tr-wifi.html
If you then drop into the OSX Terminal, you can use this command to synchronise your home directory to your iPad:
rsync -avzu --progress --delete --omit-dir-times --exclude '.DS_Store' /Users/<Your Home>/Documents/ /Volumes/<ip address>/
Where <Your Home> is the root of your home directory and <ip address> is the address of your iPad you used to map the network share.
