The Raw Read Error Rate is quite OK and is within the normal range for your model. I don't understand how the author arrives at a "status" of only 54%.
The Seek Error Rate is actually 0 and represents a perfect score, not 70%.
The End-to-End Error Count has fallen below its threshold level, so technically that would mean that the drive has failed. However, I have yet to see any case where this error has been a genuine problem. In fact I suspect that all such errors are automatically corrected.
As for the temperature, a value of 53C is not good, but it is also not unusual in a laptop environment. I don't know what you could do about it, other than to play with your fan speeds and power management settings.
