10.6.8 MAC OS x SPEND MY MONEY!

So this is basically it, im running a older macbook pro and i want to upgrade it completeley, i wanted to have it running as smooth as possible understanding that it might cost me alot of money. Now before people start saying " its better its cheaper" to buy a newer one i just want to know let you know know that yes I know! but i want to keep my baby, I love the 17 screen and itll cost me too much money to go out and buy a brand new one. Im willing to spend whatever it takes to get this to run as best as possibile. the benefits is that i have time there is no rush and i can buy parts one at a time compared to going out and dropping 7 or 800 bucks on a newer version. Moral of the story is that im trying to get this dinasour to run like a chetah with our sparring any expense im not a tech guy so ill have somebody else professionally install everything but atleast i can search for bargains on the internet, thanks so much for your help!
