I was hoping to 1) be able to use the trails on Alltrails, download/export as GPX, and import to basecamp as GPX and then onto my GPS 66SR or 2) Use caltopo (which does have the hiking trails on it) to create my way points and routes between way points, export as GPX, import to base camp as GPX and then send to my Garmin.
You can export GPX files from any source and then copy them to your GPSr\Garmin\GPX\ directory, and the device will do its best to read the data in those GPX files. Problem is, while GPX data is somewhat standardized, each source likes to format their data a little different. Important to note, a single GPX file can contain waypoints, or tracks, or routes, or geocaches, or any combination of these items. I personally like to keep my waypoints, tracks, routes etc. all separated in unique GPX files.
Start small and simple, then test results on your device, remove previous files and perform another test to observe new results, and repeat until you learn how each item interacts with your Garmin. Maybe start with important waypoints only, get those situated, then move on to tracks, and get those figured out, then maybe routes, which can be the most difficult and time consuming to master.
Try downloading a nearby track or two (no waypoints, just the track) to get started and move the GPX files to your GPSMAP 66sr\Garmin\GPX\ directory. Then, open them in 'Saved Tracks' page, and save them as 'Courses'. Then, open them in the 'Course Planner' page and save as 'Routes'. Now you can view each on the map and see how they look and work on the device, and you can select each as your destination, one at a time, using the 'Where To?' page, and practice navigating them.
Go ahead and load some waypoints separately to the same directory so they will be available on your map page.
You will not master this device over night, in a weekend, or even in a months time. But each experience will help make you more proficient with it.
