1: on my map i see dividing lines of red and blue i kno its for luxons and bulthazar or whatever but is there any thing u can do that affects them and what do they mean and how does it effect me?
Luxons vs. Kurzicks, Balthazar is something different.

Join a guild or form your own, join an alliance and fight for the side of your choice - donate your accumulated faction to that side. It doesn't affect you much unless you are in a winning alliance - you get access to a small special section of each controlled town with lowered merchant prices and fireworks.
2: where are the best places to farm?
There's an entire section of this forum devoted to this. Check it out.

4: wtf does tank mean
Stand in front of the monsters and take lots of damage without dieing.
5: what do the red bean cakes and rice wine do?
cakes cast 'sugar rush' inside the towns - it's a speed boost.
rice wine gets you drunk temporarily
