So I'm studying NTSB reports and soaking in other information about things that went wrong to try and learn from it.

Flying in and out of a busy airport requires a lot of vigilance, including ground operations. It's very easy to get your priorities out of arrangement. Not all pilots know ATC will never clear you to cross more than one runway and part of that problem is it wasn't that long ago when they would. So it's important to know what has changed so you can expect the next clearance you'll get and be prepared for it. ATC also requires you to read back all runway hold short instructions, so the analysis of this one will be interesting.
