What kind of budget are you workin with here? I think the best advice that people give on this board are those with some amount of organized plan. Make a goal for what you want out of your car and work towards it. But high profile cams and some adjustable cam gears will give you some power. If you do decide to get those, you will want the car tuned and get the timing adjusted correctly so you can see the best possible gains from the mods. But forced induction(turbo/sc) is always on the top of my list, so if you've got the funds to support a turbo motor.... go for it.
