If you've never done it before, make sure you clear the drains when you open them up. On mine, the block drains get covered by scale so they don't run when I open them. Poking a small screwdriver in the hole knocks the scale loose and I get a torrent of water out.
I'd spend the 10 minutes (OK, if it's your first time, 30 minutes) to pull the plugs and hoses, but I'd put a 40 watt trouble light in the engine compartment also. Next year when you have more time to make sure you do it right, the light won't be necessary.
