I think the most important thing to do first, if you are happy with a cloth bake, is to back up the blendcache folder immediately, if not sooner. That way you can always restore the data if for some reason it gets erased, which can happen too easily imo.
AFAIK, if you start a new bake at a different frame range using the same .blend file, the blendcache data tied to that file (its filename is in the blendcache folder name, btw) will be erased, so you need to either start with a different .blend filename (and thus a whole new cache folder), or find some way to combine the data into a common folder. This last may not be too hard since the Cloth sim looks for a cache folder with a specific name, and you can “fool” it sometimes by renaming the cache folder (I use that trick when making shape keys from Cloth sim frames). Just make sure your Cloth object name stays the same, because I’m pretty sure the sim uses that data as well.
As long as your blendcache data is preserved and you can get the sim to recognize and use it, you can set up any number of cameras to record the cloth motion from any angle you want, just like any other animation.
