Catch.pro could be a fishing site or a domain drop catching site. You are on the right lines with TalentBank.pro, it's logical and fits the extension, but a two word brandable keyphrase is significantly ahead of the game for .pro. I like the name but it's something you should register for development only.
Zakka is a Japanese and Asian fashion but it's virtually unknown in the US and Europe and has no previous sales in other extension so you have to ask yourself why would anybody consider buying it in .pro. TOEIC Test of English in International Communication is likely to be more coveted and useful in certain parts of the world than others, again I can't see any sales in other extensions.
