I'd hold off on the conversation about how to handle illness. I think it would help each of you clarify expectations, but wait until he's feeling better or gives a sign that he's in a "talking" mood. Suggestion: Don't make it a really long, drawn-out, detailed conversation where every minutia is discussed, debated, examined, etc.
Oh yeah - he's a guy so he may enjoy a little pampering more than he'll indicate. He'll want to feel self-sufficient when ill, but if you do little things for him without pointing them out, he'll probably appreciate it.
