Are you giving up Aperture?
If not, what role will Aperture play in your workflow?
This statement in particular confuses me:
In future when I import images, I will import them into a folder on my hard drive as opposed to in an Aperture library.
Your Versions (which hold your Adjustments) are not shareable with other programs. You create shareable, image-format files by Exporting your Versions ("Export" means "Make me shareable image-format files from these Versions"). There is no other way to share your Versions with other programs.
