I really enjoy the game and paid for the GW2 first, but came here to learn the game so im not total NUB at it

Anyone have any advice, all ive bought is the trilogy, as i only have 2 months to get to grips with it, is there anything i NEED to know or NEED to do, ive been hearing about HoM points?
I just want to level up quick and get some neat armour and get the mechanics and lore of the game.
yes ive read all the other new players stuff but didnt seem to answer what im looking for
Also any guilds interested in helping me out? Also im a ranger, not sure what second proff is best, but i want pets!!
