I like to use CARA to model the room and speaker positions. It gives a pretty good indication where in the room the sound field is most uniform. Put the subs where the sound field looks best, especially in the listening area.
As for the use of parametric EQ, consider this to be optional. You want to do most of the work with speaker position. You can then equalize the averaged sound field if you want but I don't think you'll find it necessary. What I do is to use a low-pass frequency that's low enough you can't localize the subs. I also don't use much drive signal to the subs. Just enough to get them moving, but not enough to tell they're on. Subtle is the key.
