When picking your starting dominion, you need to bear in mind that you can raise it, and then decide how important it is to you. Also, I believe that dominion maxs out at 10. I could be wrong, but if I am right, you probably do not want to start any higher than 8. After all, most people will build at least ten temples. If anyone can confirm this, please let me know.

That's correct. Unless you absolutely need high dominion early or are going to make a lot of holy units (since the number you can make doesn't max at 10), 10 is viable only on the tiniest Maps (Urgaia maybe), 9 for something like Aran, and in general you'd probably want at most 8.
