I want to use these LED strips in a couple costumes I'm making and I'm trying to figure out how much power I'll need. I will only be using 6 LEDs connected to a single battery pack. This process will be repeated a couple of times for various parts of the costume. Can I get away with using a 9v Battery Connector like this? Or will I absolutely need something bigger like the 12v battery pack here in order to maintain a reasonable amount of brightness/battery life?

Also, if I wanted to install an on/off switch, could I use this one? Would I need a resistor?

Don't intermix voltage (9V, 12V) with current and capacity. You can safely run single LED from a coin-size battery. You will want to connect your LEDs in series, and then in parallel.

Your LEDs have a spec - it says how much voltage they need, and how much current they eat. Plenty of LED calculators around the world.
