Wow your java moss recovered very well! Initially it was very brown and what not
Ricca has always grown out of control for me, to the point I threw it all away since I couldn't keep it attached on anything. I would wait ~1week for and see if the ricca recovers. If it doens't just chuck the yellowing sections out and the healthier parts should regrow.
As for java moss lighting, I don't think it will mind being partially shaded. It's not a high light plant. What will actually happen is that the java moss on the way bottom of that bush will slowly die off.
