Descriptive Statistics
In addition to a table with the descriptive statistics incorporating each level with each IV, should we report in the write up itself the descriptive statistics for the main effects found? That is, the table represents the statistics broken into the categories and groups within themselves, but should we report them as a whole within the write up (e.g. males (M... SD... n...)... females (M... SD... n...))?

If you make a table, all you must do is reference the table (something like, "See Table 1"). The APA manual says that if you have a compact table, you do not also needy "lengthy textual descriptions" (p. 141).

That is absolutely correct. While we are on this topic, let me point out two other related points. First, if a value is on a table, it must never be repeated in the text. The marginal means are not, of course, in your table, so you could include them in the text, but this is not required or even optimal. However, if including them helps you to remember to describe the direction of the effect in words, then do so.
