If you wire the batteries in parallel (negatives connected and positives connected) you will double the time from the two cells.Is there a way I culd use both to get twice the playing time?
Since these batteries don't have protection circuits, you'll need to get one to ensure the batteries are safe in your portable. When you get your protection circuit, that will also have the feature of being able to charge it.Can I somehow put that in my portable so I don't have to clip the battery in the outside?
That one will work for a protection circuit.
Most protection circuits do not include a charger built in. You would have to use an external charger such as a smart charger from batteryspace.comIf you wire the batteries in parallel (negatives connected and positives connected) you will double the time from the two cells.

Sorry for all the dumb questions...but the mAh on the charger you suggested is only 1600 whereas my batteries are 2100...is that a problem?Also I looked at the diagram and if I understand correctly and DC power supply is an ac-dc adapter?Not quite, those are both smart chargers. You don't want one powering another. Lithium batteries have a special set up on the current limiting to properly charge. Smart chargers are different from DC power supplies. The first one will work but you would need a separate DC power supply to power the charger and power the system while it's in use.
You would want something like this for the charger. http://www.batteryspace.com/smartcharger12afor74vli-ionpolymerrechargeablebatterypack--ullisted.aspx
And use a separate DC power supply to power the portable while it's charging. There is a diagram floating around of how to do this @ShockSlayer but I can't recall where it is. We will have a guide up sometime in the near future for power and batteries.
