All product page in the cat. box and login link in header

[matrix2223]

I was able to put a link to my all products page in my links box but I cant seem to get it to show up in the catagories box where I wanted it from the begining. I also cant seem to figure out how to put the Login/ logout link in the header. I tried to do it the same way that the others was but nothing I did worked. Can someone lead me into the right direction. Many thanks in advance.
