There's a level lockout for reaper mode. You can't be more than 4 levels over the base level of quest. As far as ransack, you can loot a chest up to 8 times in a week before hitting ransack. The timer starts from first time you open the chest. There's an option to turn on detailed chest info which will then tell you whenever you open a chest exactly when the timer will reset so you don't have to remember.
As for mana, get the highest level cleric with Divine Vitality that you can use. You don't need to hide behind them, just leave them parked at entrance if you want but they're a walking mana bank that you can refill from mid quest. Just make sure to make them rest when you do to get charges back.
Just to check, you do know when you take spell like abilities that they have to be put on shortcut bars in addition to your regular spells? Not trying to be rude, just there's so much information to take on at the beginning of this game it's easy to miss really basic things or learn them then completely forget.
If you're finding things too easy another option to add a bit of challenge is to start going into quests under level rather than at or over.
Stick at it, keep having fun and you'll find you've barely scratched the surface of what's out there.
