Bottom radiator hose cold isn't a huge deal since that's the return from the radiator, but it should warm up with the engine at normal operating temp while idling.
Some coolant will push out of the radiator when the engine is running. That's normal since there is a pressure difference as the water pump pushes fluid through the system. Also as the engine warms coolant will push out into the overflow. If the overflow is too full it will spill out. Any air in the system will prevent that coolant from being drawn back in as the system cools.
Top off the radiator before starting the engine in the morning, put the cap on and let it warm to normal operating temp (should only take 10-15 minutesnor so) Keep the hood closed to help it warm up faster. Then shut it off and let it cool. An hour or so with the hood up is fine. Make note of the fluid level in the overflow. Open the radiator and top off coolant as necessary. Then start it again and let it run to normal operating temp. This should help work any air bubbles out of the system.

They don't say to use any sealant on the head gaskets. Hopefully that doesn't cause you any issues.

Good job cranking it out so quick! You're the man!
Next time - resurface the heads and use Subaru headgaskets. EJ heads always have high and low spots, though they are robust and never crack or warp or are out of limits. I'd never install EJ heads without resurfacing, having seen those high and low spots, it seems silly not to resurface them on an engine that's so prone to blow headgaskets.
