1. P = .05 means the the probability of alpha error (rejecting the null hypothesis when it is really true) is 5 times out of 100. Whatever significance level you use is a cutting point for accepting or rejecting your null hypothesis.

2. If there is a significant relationship, larger n's will make it more likely that they will be found.

3. Haven't checked calculations, but from your data, it seems correct.
