Hi newcomer and welcome to the Tom's hardware forum.
1- None, the 1st Phenon generation don't support DDR3 RAM and 1333 in DDR2 is a waste of money.
2- The 1st option is much better but if u look the goalguy876's option is much better that yours.
3- What is ur budget? I would go with X4 945 / 4GB 1600/ 1GB 5770 or 5850.
