Looks like a good start. A bit hard for me to tell where/how the B-roman/marriage topic links in to some of this material, but I’ll trust you to sift through. You might look at sources that more squarely engage modernism and the B-roman: see Jed Esty’s, Gregory Castle, and Franco Moretti’s books. Esty’s has a chapter on Woolf’s first novel, THE VOYAGE OUT, which seems relevant, even if you’re not going to tackle that novel.
