What would be the best guitar and amp purchase?  

You play trash just like me... :) so i have 2 suggestion for you because i dont know really how much your budget.

We play same type of music genre. we both know we playing with full heavy distortion so woody sound of the guitars not really important for us (you know the expensive guitar made by good wood) so you can buy cheap guitar or custom guitars that you can designed by yourself and focus to find very good guitar pickup because that a vital thing to make thick and chunk guitar sound, if you like Active pickup (Use batteries) you can use EMG 81/85 that have really good output with very low noise but you need to replace the batteries frequently. but if you want use passive pickup you can use seymour duncan invader series (Dimebag Darrel of pantera ever use this pickup).

For the amp, if you like real Dirty and analog sound just like me you can find full tube guitar amplifier it will more respect to your picking techniques. so what you training for years not will digitalized by damn solidstate amplifiers. but remember you need warming up the head before you hit a full distortion downstrokes picking to that amp.
