DO NOT START THE CAR AGAIN UNTIL YOU CHECK THE TIMING BELT!
You have a misfire code on all 4 cylinders. VERY few things can cause all 4 cylinders to misfire. Fuel delivery, major electrical issue or component or a timing issue. I'm thinking it's the latter.
I'm not sure of the codes (you should really post up the codes you pulled), but usually when the car throws a crankshaft sensor code, it's usually a "crankshaft position" code prompting you that the crank is shouting that it's out of sync with the camshaft position sensors (which may or may not be out of time as well). You could have very well skipped a couple teeth on the crankshaft sprocket alone, causing the misfires. If it skips more than 3 teeth, that usually ends in catastrophic failure (bent valves, possibly cracked pistons, etc.)
I would post the codes you got so we can check them against the Subaru database (I just get the code from those readers, and then look it up with Subaru as the code readers are usually a more "generic" description.)
DO NOT start up the car again until you can verify that your timing belt, cams, tensioner, etc. are all properly timed and aren't faulty. Use an actual Subaru Shop manual for this as they have the number of teeth between each mark that you can verify. I simply had a weak tensioner on my old 04 XT, and it skipped 3 teeth on the crank sprocket. I got misfires, a couple other sensors freaked out as well as the crank sensor code as you described. One more tooth and I would have had catastrophic failure.
One thing I learned (and used to do this frequently) is that you can throw parts at the car all day long and hope that one of them will fix the issue. Sometimes is works, most of the time, you end up spending hundreds on parts you replace, then spend more on an issue completely unrelated. Happened to me. I was getting low power from my 04 XT, replaced the turbo, coil packs, MAF, O2 sensors, etc. Cost me about $1700 before I gave up. Guess what? Found out a month later it was simply a crack in my downpipe. $50 later for a second-hand one and my issue was fixed. I pretty much threw away $1700 because I didn't do more research, and didn't do enough troubleshooting. Lesson learned.
Troubleshoot first. Gather info, diagnose as much as you can, and ask for help (as you are). Hopefully, you'll find the issue and can resolve it without too much hassle.
