I don't know how to build chars, or how to play the game as most do.

I read the basics, I understand how to gain exp/levels

otherwise, I'm pretty much shit out of luck.

I just need like stat allocation basically and what I should do from what to what

I have a 500 fg budget on gear

if you go for a hybrid:

The Rogue Caster Guide by JayKwik

Eekzies Rogue Caster Guide by eekzie

for melee read this first, because a fighter will most likely be the better choice for going the melee path these days:

Myaddiction's Melee Guide (v1.07) by MyAddiction

Which is better barbarian or fighter then?

imo rogue = cheapest character to start with
