What are the odds and expected frequency off a suited pair occurring in an 8 deck shoe when only two cards are dealt, one to player one to house.

Do you mean identical cards? If so, assuming a randomly-shuffled, full 8-deck shoe, the probability is 7 in 415. There are 416 cards in an 8-deck shoe, and one is the first card out. Once that card is out, there are only 7 left in the deck that match it out of 415 remaining. This changes, sometimes dramatically, as cards are dealt.

Is that correct, 13 cards in a deck and potential pairs of; J J, Q Q, K K.

There are 52 cards in a deck, if I'm doing the math properly. Not sure where the jacks queens and kings comment comes into play, though.

the probability is 7 in 415

There are 13 possible pairs in 8 decks, 1 ~ 10 then 3 picture cards.

Your first card is any one of 52. After that card is dealt, there are only 7 identical cards left.
