Firstly, truth has absolutely nothing to do with the existence of any person or being at all. In a world without intelligence what-so-ever truth is still what actually is. Any statement that accurately describes any aspect of anything at all is "true".

As for morality:

1. All values exist as a relationship between desires and states of affairs and/or objects.
2. Good is that which fulfills the desires in question. Bad is that which thwarts the desires in question. (Good for me is that which fulfills the most and/or strongest of my desires, Good for you is that which fulfills the most and strongest of your desires - This is the common form of "good")
3. Morality is a subset of value dealing with shared values (good for us).
4. Therefore, that which is morally good (good for us) is that which fulfills the most and/or strongest desires from competing sets of desires (has the greatest positive value).

I would argue truth is a artifact of an perceptive mechanism evolved for the purpose of organizing mental models of the material world. Without intelligence, the rest of the material world continue to exist, and continue to behave. But the organized perception would not exist and so truth would not exist. So truth does not exist regardless of whether god exists. Truth only exist because you exist, and truth appears to be shared only because the perceptive mechanisms of your peers are similar, and when conditioned by similar social programing, generate similar communicable artifact.
