I can suggest an even better idea.
Buy yourself an apple 12" iBook or an IBM thinkpad for around $1,500.
Maybe even buy a second hand laptop for much less.
(I recommended the above because they are small, have 5+ hours battery life and weigh around 2kg all up)
Then go on to the net and download all those documents (maybe minus ERSA, have not tried that as I use jepps)
FOR FREE!!!!!!
It will take up less space and weigh less than the binders. It will all fit in your navbag. Print out the stuff that you need. And because it is in your computer, you can use search functions to find bits and pieces.
