What should I buy guitar gear wise?

I'd get the wah or the overdrive, your guitars aren't worth a pickup upgrade. The overdrive and the wah can both be used as solo boosters. With an old fashioned wah you can leave the pedal rocked forward and it boosts your mids. You can stack the overdrive on top of your other distortion giving you a lot of distortion and sustain, it sounds really good. It's bright and cuts through great.
