have been spraying into throttle bodies for years, never had a problem messing up plugs. but if you are insistent, you can remove the throttle body from the intake and clean it outside of the car. note that you may need to replace throttle body gasket after removing it depending on how well it comes apart and how well it seals once put back together.
Here's one more idea if you're careful, though i don't think i recommend this. You could stuff a small clean shop rag just through the throttle flap so it's actually in the intake manifold (make sure you can get it back out when you're done) and then spray all through the throttle body. The rag should soak up any excess fluid and then pull it back out when you're done. The reason i don't recommend this is because you may get fibers or other unfiltered debris in the intake and then into the cylinders which could theoretically scratch your cylinder walls and compromise compression to a degree or cause you to burn oil (yeah i guess it's not likely but it has to be possible).

Well you hit all the major ones, could be crank position sensor, ignition module, a bad coil pack (it should have 3), you need to check that you have spark to each plug while the engine is turning over (!!!be careful as this will hurt if you get shocked!!!), this will rule out coil packs. if you have no spark to any plug your looking at a bad ingnition module (which is what the coil packs bolt to). Hope this gets you on the right track!
