I'm currently doing everything you talking about now. First off the dash pad comes off very easy more than likely all ur tabs along the windshield will be broken and will need to be epoxy back in place. Take the dash to the car wash and spary it down to the black abs plastic the paint will come off in sheets. Repaint with sem paint and adhesion promoter. Far as carpert go to
www.stockinteriors.com that pretty much were everyone gets aftermarket carpet. I personally got the ultra plush carpet upgrade and mass backing I'd get this regardless just for the extra sound deadening. I'm going to start my own trend in the under construction soon with pics of everything I've done so far.
