Hi Coal:
MY OPINION ONLY is that I would get a surge suppressor, even if only for the TV, BD player, etc. Some feel that a surge protector is unnecessary and will even limit peak electrical draw from amps, receivers and subs.
There are some that believe that cable types make a difference, but of them, the majority involve analog cables.
An HDMI cable simply transfers Ones and Zeros.... so any cable should do if you don't have any really long runs.
Many like
Monoprice for cables. Their inexpensive (but work just fine). Sometimes, I've found their cables to be a little stiff, but they're still my primary cable source anyway.
