Discharge to 3v per cell!?? I wouldnt have said thats a good idea, ideally you dont want a lipo cell to drop below 3.3v per cell, 3v at absolute max!
regarding c charge rate, importantly make sure you check what the charge rate is for your lipo,, if its 1c dont be tempted to up the charge rate, also from what I've read if you want longevity from your lipo dont charge at more than 1c anyway.
If you are storing your lipo for say 3 weeks or more its a good idea to charge/discharge them to around 3.8v per cell
