dunno if removing the front reo is such a good idea, as its there to absorb hits so your chassis doesn't bare the brunt of a frontal. but other than that that list sounds awesome way of goin about it.
how far you wanna go really depends on how much of a daily drivable street car you wanna keep it. I've found factory GTR rims to be the best value for money, as they're about 6 or 7 kgs a corner and really cheap compared to wheels sold as lightweight rims.
