Is renaming a power in your purchase log/Roster, but putting an abbrievation for what it actually is, such as ATK for a "Tractor Beam" type technology, as it were, that will be that power?

You need to use full names of the things you're purchasing in your Log for record keeping. I'd say the same goes for the first post of your Roster for clarity, but when describing the moves and such in a second or third post you're more than welcome to abbreviate and call them something different to explain what they are.
