but really, bottom line, to save money, you have to have a goal/plan before you mod. many people (including myself) have wasted money on parts that get upgraded (for me-ssic<wbs genI<wbs gen3).
pem/rocker setup would be a nice gain. but if you really want to get the most out of the car, and the money isnt a huge issue, go for the headers. i would go for S&S or SLP rather than the pacesetters, unless you get the GT headers (i thought one of the vendors were coming out with those). the primaries are too large for a n/a car w/o cam/heads IMHO.
