No, it doesnt work with DRMd audiobooks, I suspect none of the iTunes downloaded books would work with anything else except iPod on Apple devices. Most of mine are not DRMd, but those that are cannot be played in this app. I have a very few downloaded via iTunes, the rest are sourced elsewhere and converted to m4b, bookmarkable, via Audiobook Builder.
As to whether now playing is altered... You are using a completely different application to access a different file, so when you return to itunes, whatever you were playing last will be whats showing.
