There is a lot more to tone than just pedals... However... if you want to sound like Stevie, get a Strat (you don't NEED one but the single coils were part of his tone)... an amp modeler that has a decent classic tube amp on it (cheaper than buying the tube amp). Set up so your guitar sounds clean but slightly dirty then dial in just a touch of overdrive with an overdrive pedal... adjust to the sound that you specifically want... add a wah pedal to get his wah tones. Stevie also used HEAVY gauge strings (.13's) thats Stevies tone in a nutshell... i'm not 100% positive of the way he got his tone... but that's how I get his tone. Close enough for me. hope that gives you something to experiment with. By the way... a good overdrive pedal is the TubeScreamer by Ibanez...
