Warcraft 3 MODs

Hi. I write here couse I need help with modifying a little bit w3tft. I need 3 races with changed skills and names. First: unholy aura, trueshot aura, dodge, suicide. Second: fire breath, impale/shadow srike, bash and lightning. Third: entangling roots, invisibility, serpent ward and locust swarm. Also I need to set xp needed (more xp to lvl-up) and delete shopmenu. I tried to do it alone, but I'm still newbie at it, so if anyone of you could help me do it, I'd very grateful. I hope I will find helpful people here ^^
