A baker's half dozen is a group of seven items, the concept being that it is one more than a half dozen.
It depends on how you are using the word "half". Most of the time it is used as an adjective. If the word is being used as part of a mixed numeral, then the word is preceded by "and a": "I used three and a half cups of flour in the cake." If the word is being used to denote 50% of a single countable item, then you may use "a half" or "half a(n)", but never "a half a(n)": "We will be there in half an hour." "We will be there in a half hour." It is never correct to use "We will be there in a half an hour." If the word is being used to denote 50% of an uncountable or plural countable item, then the word is followed by "the" or "of the": "Jane used up half the napkins during dinner." "Bob lost half of his marbles in the game." Idiomatically, there exists "half and half", which is approximately 50% cream and 50% milk. This is a noun and is used the same way as the word "milk" with nothing extra needed: "I poured half and half in my coffee."
