I can only provide you with some basic tips:
1. Clean dirt and other nasty stuff from your 360, especially if it's near the vents.
2. Keep it away from your carpet or floor. A table should do fine.
3. When closing the disc drive, press the button next to the drive instead of pushing the drive closed with your hand.
4. Don't rest anything on your 360, especially food/drinks. It can be tempting, but don't do it.
5. Make sure the room is well ventilated/cool.
