dude.
looking at your APC model, you're a long way off having a character modelled to put in FPSC.
You need to start using the search function. People have posted tutorials on this question since FPSC first came out.
It may come as a shock, but we are all busy people too. Very few people are going to take the time to write you a bespoke tutorial when there are already perfectly good ones out there already.
Secondly. How can we tell you how to get a character into FPSC without knowing what program you're using to make the character?!
