I use the Standard Catalog of World Paper Money (Krause Publications). They are available for General Issues 1368-1960 and for Modern Issues 1961-Present. I personally like the e-version, which can be downloaded on your computer (PDF), but they are also available in print.
Foreign and fairly recent notes like these can be bought individually or in bulk lots on eBay. It varies one note from the other but they typically sell from $0.75 - $2.00 each. If looking to sell as one lot, I'd list at $1.50 times however many notes you have and see if there are any takers.
