Oh, and I hear from a feat in one sources that allows you to maximize healing depending on your charisma modifier. Maybe someone else does know more details about it.

Unfortunately, I have not that much more advice for you, except:
How much is little downtime? Remember that creating magic items requires 1 day per 1.000 gp of cost. Potions and Scrolls (and later Wands) are often cheaper than that and can be made within one day. And I believe in 3.5 you are allowed to distribute the time as you see fit without wasting the creation process.
