I quite liked The Reader when it came out, but I haven’t seen it in almost a decade. As to whether or not Ewan will be back, I think he most likely will, but I’ve also seen it suggested that this might be set before TPM and follow his training. That seems doubtful to me, though, given Liam Neeson’s age. The Qui-Gon character is so beloved among the PT crowd that I can’t see them recasting the role or writing him out, so in guessing they’ll just cover that story in other media.
