I'm 38, but I don't really have confidence that I can 3 star anyone left. Should I do one of those scouting attacks or just wait?
Yes, do a scouting attack if you would. Here's what you can do for Fudd. He's trying to figure out how goblins will do springing #5's CC.
Build a crap load of goblins, and maybe a few giants. Release some goblins at the bottom middle, by the opening guarded by a cannon, so the goblins target the low level elixir storage beneath the archer queen.
Try releasing a group of 4 quickly, a pause, another group of 4, see how far they get. You'll probably trigger AQ and maybe part of CC, so then drop 1 unit at top of map to pull them away from bottom. Then repeat, but this time maybe drop a giant to head at cannon then drop about 5 goblins at once, so we can see how much it helps with a giant drawing fire.
Basically we want info on how quickly the goblins die, how many groups will it take to trigger the CC fully. Plus we want to know what is in the CC.
With any extra units you could scout goblins into the other openings and look for bombs and springs that way.
Edit to add: Fudd, if you want it done differently just post.
