Will be getting a uhd blu ray player when available and my hdmi cables are a few years old now(1.3 I think) will I need a better spec cable for player to tv?
These logos are the only thing that matters with regard to cables, if a product doesnt have them then they are not official and cant be trusted.
Anything else in a sales add is nonsense designed to mislead... HDMI :: Manufacturer :: HDMI 1.4 :: Finding the Right Cable
Try the ones you have first, chances are they will be fine.
In the unlikely event they are not, shop using the cable guidelines above and look for the logo, ignore all other claims about the product, they will be lies.
