The fastest way to earn Turbine Points is to go outside and walk down your street and ask any of your neighbors if they would be willing to pay you to rake their leaves or if they have any other chores that you could do for them to earn a little spending money. Then take the money you earn and purchase either a game card at Target, Walmart, or if you have a credit card either get the mithrel edition or steam edition packages. Remember that this is a game that you are playing for fun not a job where you get paid for your time. Spending to much time grinding at things you dont enjoy defeats the purpose of playing a game. Once you have a nice base of 1000 Tp from your purchases any needed TP should come easily as you level up your charaters. A wisely spent 10 to 20 dollar investment can take you all the way to 65 easily.
Try all classes that sound interesting to you until lvl 25, completing any deeds that you have over half way done from just questing as you go, this should not be to much of a grind. Check out a few servers also to lvl 25 to get a feel for what they are like so you find a server that you feel at home with. Then just play the game and have fun. Christmas is coming up soon. See if you can get a family member to get you a game card as a gift.
The most important thing is to not make this game into a job because the return on your time is just not worth it.
