I wouldn't panic based on that. My anal area was frequently moist and irritated after surgery, and still gets that way sometimes (particularly if I pass a lot of gas or have several bowel movements in a day), even more than 2 months after the fact.
As for the light pink drainage, it's most likely normal too. You could get drainage for a while. The extended drainage is one of those little details that doctors aren't so good at telling patients about. If it's light pinkish, I'd give it another week or two and see if it decreases or subsides altogether. What you want to watch out for is anything thick and yellow that looks like pus or any lumps that form around the anus since they could be signs of infection.
