Fortunately, the APA Publication Manual 6th Edition has everything you need. It's not perfect, but it is the most up-to-date and correct source for all this info. You should be able to get it at any library. It has an example manuscript as well as description.
I second Rose and Peter's suggestions; these are what I do. You can also look at recent papers in any journal that uses APA style, and mimic the way they report statistics.
Also note, however, that APA style is fairly minimal; there are a lot of potentially useful things that APA doesn't require but that more and more statistics people nowadays are saying should be reported. The APA guidelines tend to be a bit behind the times. There is a lot of recent literature, blog posts, etc., on the value of reporting things like confidence intervals, showing full distributions of the data (rather than just measures of central tendency) in the figures, etc.
