I need your help!!!

You all know I'm rubbish when it comes to understanding really important information when it comes to uni. So I need your help and I'd appreciate it like... well, there's not a word for it but extremely is sort of close to it.

THIS IS THE INFORMATION WHICH I DON'T UNDERSTAND

The questions I need answered are:

1. Do I have to have an unconditional offer from the uni I want to go to before applying? Which means - do i need to have sent my grades to the school before I apply for tuition fee help?
2. Do I need to pay the tuition fee thing back? I don't think so but I need to be really sure...

... I think those are the only things I don't understand.
