recommended parts with sportline install?

You will have to get the car aligned after the springs settle. CC place may be necessary but you won't know until you take it to the alignment shop.

Other than that, you shouldn't need anything, unless any suspension parts are worn and need replacing while you are there.

What he said. I'd say with sportlines you will probably end up needing the Caster/camber plates but you won't know till you go to get an alignment. Which you will definetly need after the spring install.
 
I have a ProKit and need CC plates so I'd also suggest you get some. Even if they are not needed for 'spec' alignment settings, they are needed for performance-oriented settings.

Poly Isolators are nice but will add a little height to things. If yours are in okay shape and money is real tight, you can likely get away with the stock isolators (even if they require some patch work).

And that's about all I used on my last spring install.

Good luck.
