Hey, as far as custom profile I won't be much help there since I have not tried to do my own but for the little icons next to the pets they own when you create your siggy there should be a little smilies delio over to your right >> kind of like where you make a post where you can select from. I will doubt check this right now for you and we will see if get it to work. The birthday banners you can make but googling "Brithday tickers" or "tickers" once you create the ticker they give you a code that you copy paste into your siggy. I hope this helpes =D
