To wire a light to be switched from more than one place requires a lot of extra wiring (14/2 to the first switch and then 14/3 to the light and each additional switch) and 2, 3, and 4 way switches. By looking at the x10 website it looks like a lot of the wiring would be eliminated, because the switch (controller) would only have to be powered and then the light powered and the controller tells the light to come on instead of a wire from the switch to the light and a wire from switch to switch. Clear as mud??? Wiring 2, 3, and 4 way switches is not one of my strong points. I always have to use a template on those.

You can save room in the conduit by not running your neutral lines to the switch box. Leave your neutrals in the ceiling and only run the wires you need for the switch. There's no need for a neutral wire in the box if all you have are switches.
You can save further room in the box by splitting your various lights out at the box. For example, run a hot wire into the box and split that hot wire for the porch light, ceiling light, and lamp lights That cuts you down to 5 wires total. 1 line hot wire, 2 runners for the 3 way switch, 1 switched hot for the porch, and 1 switched hot for the lamp lights. 5 wires in a 1/2" conduit (not romex) should fit comforably.
Be sure to use different colors so you know what's what on the other end.
