Welcome to the site!
To answer your question - personally I would go with either sway bars or shocks. The sway bars will make the car sit heaps flatter around corners, and make it feel like it has loads more grip even if it doesn't!
My old MX-5 had Koni shocks and Eibach springs, this worked well enough but I think the Tein coilovers aren't much more and seem to work much better.
I'm running Tein Super Streets now and love 'em.
