hello im using a pi2 that has and sd card in it with kodi on it i wanted to know if i use another sd card and put retropi onto it and just switch out the two different cards that i want to use. the install goes onto card not the pi correct? so it wont be overwriting anything? any information would be great

Correct. The Pi has no onboard storage, everything goes onto the SD card.
ok great so i can use two different cards

also can i hook up my ps3 controller to the pi2? idk if it has bluetooth compatibility or i need a Bluetooth dongal.

The R-Pi2 does not come standard with bluetooth. If you are running RetroPie on the same board, I recommend upgrading to the R-Pi3, as it clocks in more processing power.
I hope this helps you out.
thanks i got a usb controller lastnight and hooked it up it works great. but i noticed that u run roms off of usb stick dont that make it any slower then just installing them on pi sdcard?
