What do you need to do online?
The sent me PPS forms to fill out and return in person for an interview. As I was working part time and my youngest child was 7 they also required me to register for an employment agency (not sure why, it was just one of their strange rules).
I had to apply for FTB A and B stuff online as I didn't qualify when I was married.
This was in 2011. Things may have changed since then.
