Q:
Obviously, a Wizard can't cast in armor freely (spell failure and such). BUT what about items like wands and scrolls? I've checked SRD but I want to make sure. Scrolls are like spells, so casting in armor an arcane spell from a scroll will have spell failure but using a wand will not, right?
2nd Q:
A major scroll can have up to 6 spells on it. That means 6 charges or 1 charge but you can choose from 6 spells?
