I currently have a Lumia 635 running 8.1. I'm about to get the 650. Can I take the SD card I have in the 635 and just stick it the 650, or is it better to insert a blank card and re-download all my apps?

You need to download apps again.
When you store apps on SD it create entry in phone and store data on SD. When you switch SD then data may available to your phones but there is no entries in your phone means it does not shoes in start/app list and you can not access it.
So best suggestion is format SD and redownload apps
