If you're in New York over the next few months, you should make your way down to The Museum of Jewish Heritage near Battery Park. They have an exhibit entitled Woman of Letters: Irène Némirovsky and Suite Française that displays the suitcase in which the now famous manuscript was found, along with the manuscript itself. If you can't make it in person, do check out their website where you can see both artifacts online plus family photos and learn more about her life and work. (thanks to the Literary Saloon for the link).
And if you enjoyed reading Suite Française, do check out some of her other books that have recently been brought back into print: David Golder, Fire in the Blood, Le Bal, The Couriloff Affair (out this October) and All Our Worldly Goods (out this November).
