Does this CV boot need replacing?

Hi, I've taken some piccys of it, I saw a couple of places where a small amount of grease may be seeping out but nothing big;

OK thanks I will have a go at putting a new one on. I've looked on the gsf car parts site to order a new kit, is it the inner cv boot or the outer cv boot that I need? Also what is the difference between the two just so i know?
